I need to generate a file for Excel, some of the values in this file contain multiple lines.
there's also non-English text in there, so the file has to be Unicode.
The file I'm generating now looks like this: (in UTF8, with non English text mixed in and with a lot of lines)
Header1,Header2,Header3
Value1,Value2,"Value3 Line1
Value3 Line2"
Note the multi-line value is enclosed in double quotes, with a normal everyday newline in it.
According to what I found on the web this supposed to work, but it doesn't, at least not win Excel 2007 and UTF8 files, Excel treats the 3rd line as the second row of data not as the second line of the first data row.
This has to run on my customer's machines and I have no control over their version of Excel, so I need a solution that will work with Excel 2000 and later.
Thanks
EDIT: I "solved" my problem by having two CSV options, one for Excel (Unicode, tab separated, no newlines in fields) and one for the rest of the world (UTF8, standard CSV).
Not what I was looking for but at least it works (so far)
You should have space characters at the start of fields ONLY where the space characters are part of the data. Excel will not strip off leading spaces. You will get unwanted spaces in your headings and data fields. Worse, the " that should be "protecting" that line-break in the third column will be ignored because it is not at the start of the field.
If you have non-ASCII characters (encoded in UTF-8) in the file, you should have a UTF-8 BOM (3 bytes, hex EF BB BF) at the start of the file. Otherwise Excel will interpret the data according to your locale's default encoding (e.g. cp1252) instead of utf-8, and your non-ASCII characters will be trashed.
Following comments apply to Excel 2003, 2007 and 2013; not tested on Excel 2000
If you open the file by double-clicking on its name in Windows Explorer, everything works OK.
If you open it from within Excel, the results vary:
You have only ASCII characters in the file (and no BOM): works.
You have non-ASCII characters (encoded in UTF-8) in the file, with a UTF-8 BOM at the start: it recognises that your data is encoded in UTF-8 but it ignores the csv extension and drops you into the Text Import not-a-Wizard, unfortunately with the result that you get the line-break problem.
Options include:
Train the users not to open the files from within Excel :-(
Consider writing an XLS file directly ... there are packages/libraries available for doing that in Python/Perl/PHP/.NET/etc
After lots of tweaking, here's a configuration that works generating files on Linux, reading on Windows+Excel, though the embedded newline format is not according to the standard:
Newlines within a field need to be \n (and obviously quoted in double quotes)
End of record: \r\n
Make sure that you don't start a field with equals, otherwise it gets treated as a formula and truncated
In Perl, I used Text::CSV to do this as follows:
use Text::CSV;
open my $FO, ">:encoding(utf8)", $filename or die "Cannot create $filename: $!";
my $csv = Text::CSV->new({ binary => 1, eol => "\r\n" });
#for each row...:
$csv -> print ($FO, \#row);
Recently I had similar problem, I solved it by importing a HTML file, the baseline example would be like this:
<html xmlns:v="urn:schemas-microsoft-com:vml"
xmlns:o="urn:schemas-microsoft-com:office:office"
xmlns:x="urn:schemas-microsoft-com:office:excel"
xmlns="http://www.w3.org/TR/REC-html40">
<head>
<style>
<!--
br {mso-data-placement:same-cell;}
-->
</style>
</head>
<body>
<table>
<tr>
<td>first line<br/>second line</td>
<td style="white-space:normal">first line<br/>second line</td>
</tr>
</table>
</body>
</html>
I know, it is not a CSV, and might work differently for various versions of Excel, but I think it is worth a try.
I hope this helps ;-)
In Excel 365 while importing the file:
Data -> From Text/CSV:
-> Select File > Transform Data:
In the Power Query Editor, right hand side at "Query Settings", under APPLIED STEPS, on "Source" row, click the "Settings icon"
-> In the line break dropdown select Ignore line breaks inside quotes.
Then press OK -> File -> Close & Load
It is worth noting that when a .CSV file has fields wrapped in double quotes which contain line breaks, Excel will not import the .CSV file properly if the .CSV file is written in UTF-8 format. Excel treats the line break as if it were CR/LF and begins a new line. The spreadsheet is garbled. That seems to be true even if semi-colons are used as field delimiters (instead of commas).
The problem can be resolved by using Windows Notepad to edit the .CSV file, using File > Save As... to save the file, and before saving the file, changing the file encoding from UTF-8 to ANSI. Once the file is saved in ANSI format, then I find that Microsoft Excel 2013 running on Windows 7 Professional will import the file properly.
Newline inside a value seems to work if you use semicolon as separator, instead of comma or tab, and use quotes.
This works for me in both Excel 2010 and Excel 2000. However, surprisingly, it works only when you open the file as a new spreadsheet, not when you import it into an existing spreadsheet using the data import feature.
On a PC, ASCII character #10 is what you want to place a newline within a value.
Once you get it into Excel, however, you need to make sure word wrap is turned on for the multi-line cells or the newline will appear as a square box.
This will not work if you try to import the file into EXCEL.
Associate the file extension csv with EXCEL.EXE so you will be able to invoke EXCEL by double-clicking the csv file.
Here I place some text followed by the NewLine Char followed by some more text AND enclosing the whole string with double quotes.
Do not use a CR since EXCEL will place part of the string in the next cell.
""text" + NL + "text""
When you invoke EXCEL, you will see this. You may have to auto size the height to see it all. Where the line breaks will depend on the width of the cell.
2
DATE
Here's the code in Basic
CHR$(34,"2", 10,"DATE", 34)
I found this and it has worked for me
$delimiter = ',';
$enc1 = '"';
$enc2 = '""';
Then where you need to have stuff enclosed
$myfile = ('/path/to/myfile.csv');
//erase any previous contents
$fp = fopen($myfile, 'w+');
fwrite($fp, $enc1 . 'Column Heading 1' . $enc1 . $delimiter );
//append to new file
$fp2 = fopen($myfile, 'a');
fwrite($fp2, $enc1 . 'Column Heading 2' . $enc1 . $delimiter );
.....
fwrite($fp2, $enc1 . 'Last Column Heading' . $enc1 . $delimiter. PHP_EOL );
Then when you need to write something out - like HTML that includes the " you can do this
fwrite($fp2, $enc2 . $myhtmlstring . $enc2 . $delimiter);
New lines end with . PHP_EOL
The end of the script prints out a link so that the user can download the file.
echo 'Click here to download file';
Test this:
It fully works for me:
Put the following lines in a xxxx.csv file
hola_x,="este es mi text1"&CHAR(10)&"I sigo escribiendo",hola_a
hola_y,="este es mi text2"&CHAR(10)&"I sigo escribiendo",hola_b
hola_z,="este es mi text3"&CHAR(10)&"I sigo escribiendo",hola_c
Open with excel.
in some cases will open directly otherwise will need to use column to data conversion.
expand the column width and hit the wrap text button. or format cells and activate wrap text.
and thanks for the other suggestions, but they did not work for me. I am in a pure windows env, and did not want to play with unicode or other funny thing.
This way you putting a formula from csv to excel. It may be many uses for this method of work.
(note the = before the quotes)
pd:In your suggestions please put some samples of the data not only the code.
UTF files that contain a BOM will cause Excel to treat new lines literally even in that field is surrounded by quotes. (Tested Excel 2008 Mac)
The solution is to make any new lines a carriage return (CHR 13) rather than a line feed.
putting "\r" at the end of each row actually had the effect of line breaks in excel, but in the .csv it vanished and left an ugly mess where each row was squashed against the next with no space and no line-breaks
For File Open only, the syntax is
,"one\n
two",...
The critical thing is that there is no space after the first ",". Normally spaces are fine, and trimmed if the string is not quoted. But otherwise nasty. Took me a while to figure that out.
It does not seem to matter if the line is ended \n or \c\n.
Make sure you expand the formula bar so you can actually see the text in the cell (got me after a long day...)
Now of course, File Open will not support UTF-8 Properly (unless one uses tricks).
Excel > Data > Get External Data > From Text
Can be set into UTF-8 mode (it is way down the list of fonts). However, in that case the new lines do not seem to work and I know no way to fix that.
(One might thing that after 30 years MS would get this stuff right.)
The way we do it (we use VB.Net) is to enclose the text with new lines in Chr(34) which is the char representing the double quotes and replace all CR-LF characters for LF.
Normally a new line is "\r\n". In my CSV, I replaced "\r" with empty value.
Here is code in Javascript:
cellValue = cellValue.replace(/\r/g, "")
When I open the CSV in MS Excel, it worked well. If a value has multiple lines, it will stay within 1 single cell in the Excel sheet.
you can do the next "\"Value3 Line1 Value3 Line2\"". It works for me generating a csv file in java
Here is an interesting approach using JavaScript ...
String.prototype.csv = String.prototype.split.partial(/,\s*/);
var results = ("Mugan, Jin, Fuu").csv();
console.log(results[0]=="Mugan" &&
results[1]=="Jin" &&
results[2]=="Fuu",
"The text values were split properly");
Printing a HTML newline <br/> into the content and opening in excel will work fine on any excel
You could use keyboard shortcut ALT+Enter.
Select the cell you wish to edit
enter edit mode either by double clicking it or pressing F2
3.Press Alt+enter. This will create a new line in cell
I am having a very hard time trying to write out an xml file from asp vbscript to a text file using the Scripting.FileSystemObject. The issue is the less than and greater than chars. In order for me to add these characters to variables in the code i need to use < ; > ;. This causes a problem when writing the text. The results look like this
<copyright>request copyright</copyright>
<lastBuildDate>10/26/2012</lastBuildDate>
proper format should be as such
<copyright>request copyright</copyright>
<lastBuildDate>10/26/2012</lastBuildDate>
Is there some sort of trick to converting those segments while writing the text file, or do i need to do something a bit more extravagant?
Thanks in advance!
When writing in the TextStream, you could just surround your variables with two calls to Replace
TextStream.Write Replace(Replace(myString, "<","<"),">",">")
This way the variables aren't altered, but the written out data uses the right characters.
Try this:
Dim objStream
Set objStream = CreateObject("ADODB.Stream")
objStream.CharSet = "utf-8"
objStream.Open
objStream.WriteText "testdata"
objStream.SaveToFile "C:\test.txt", 2
So I have an ASP.Net (vb.net) application. It has a textbox and the user is pasting text from Microsoft Word into it. So things like the long dash (charcode 150) are coming through as input. Other examples would be the smart quotes or accented characters. In my app I'm encoding them in xml and passing that to the database as an xml parameter to a sql stored procedure. It gets inserted in the database just as the user entered it.
The problem is the app that reads this data doesn't like these characters. So I need to translate them into the lower ascii (7bit I think) character set. How do I do that? How do I determine what encoding they are in so I can do something like the following. And would just requesting the ASCII equivalent translate them intelligently or do I have to write some code for that?
Also maybe it might be easier to solve this problem in the web page to begin with. When you copy the selection of characters from Word it puts several formats in the clipboard. The straight text one is the one I want. Is there a way to have the html textbox get that text when the user pastes into it? Do I have to set the encoding of the web page somehow?
System.Text.Encoding.ASCII.GetString(System.Text.Encoding.GetEncoding(1251).GetBytes(text))
Code from the app that encodes the input into xml:
Protected Function RequestStringItem( _
ByVal strName As System.String) As System.String
Dim strValue As System.String
strValue = Me.Request.Item(strName)
If Not (strValue Is Nothing) Then
RequestStringItem = strValue.Trim()
Else
RequestStringItem = ""
End If
End Function
' I get the input from the textboxes into an array like this
m_arrInsertDesc(intIndex) = RequestStringItem("txtInsertDesc" & strValue)
m_arrInsertFolder(intIndex) = RequestInt32Item("cboInsertFolder" & strValue)
' create xml file for inserts
strmInsertList = New System.IO.MemoryStream()
wrtInsertList = New System.Xml.XmlTextWriter(strmInsertList, System.Text.Encoding.Unicode)
' start document and add root element
wrtInsertList.WriteStartDocument()
wrtInsertList.WriteStartElement("Root")
' cycle through inserts
For intIndex = 0 To m_intInsertCount - 1
' if there is an insert description
If m_arrInsertDesc(intIndex).Length > 0 Then
' if the insert description is of the appropriate length
If m_arrInsertDesc(intIndex).Length <= 96 Then
' add element to xml
wrtInsertList.WriteStartElement("Insert")
wrtInsertList.WriteAttributeString("insertdesc", m_arrInsertDesc(intIndex))
wrtInsertList.WriteAttributeString("insertfolder", m_arrInsertFolder(intIndex).ToString())
wrtInsertList.WriteEndElement()
' if insert description is too long
Else
m_strError = "ERROR: INSERT DESCRIPTION TOO LONG"
Exit Function
End If
End If
Next
' close root element and document
wrtInsertList.WriteEndElement()
wrtInsertList.WriteEndDocument()
wrtInsertList.Close()
' when I add the xml as a parameter to the stored procedure I do this
cmdAddRequest.Parameters.Add("#insert_list", OdbcType.NText).Value = System.Text.Encoding.Unicode.GetString(strmInsertList.ToArray())
How big is the range of these input characters? 256? (each char fits into a single byte). If that's true, it wouldn't be hard to implement a 256 value lookup table. I haven't toyed with BASIC in years, but basically you'd DIM an array of 256 bytes and fill in the array with translated values, i.e. the 'a'th byte would get 'a' (since it's OK as is) but the 150'th byte would get a hyphen.
This seems to work for long dash to short dash and smart quotes to regular quotes. As my html pages has the following as the content type. But it converts all the accented characters to questions marks. Which is not what the Text version of the clipboard has. So I'm closer, I just think I have the target encoding wrong.
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
System.Text.Encoding.ASCII.GetString(System.Text.Encoding.GetEncoding("iso-8859-1").GetBytes(m_arrFolderDesc(intIndex)))
Edit: Found the correct target encoding for my purposes which is 1252.
System.Text.Encoding.GetEncoding(1252).GetString(System.Text.Encoding.GetEncoding("iso-8859-1").GetBytes(m_arrFolderDesc(intIndex)))
If you convert to a non-unicode character set, you will lose some characters in the process. If the legacy app reading the data doesn't need to do any string transformations, you might want to consider using UTF-7, and converting it back once it gets back into the unicode world - this will preserve all special characters.
i have a page that allow user to upload an excel file and insert the data in excel file to the SQL Server. Now i have a small issue that, there is a column in excel file with values, such as "001", "029", "236". When it's insert to the SQL Server, the zero in front will be ignored in SQL, so the data would become "1", "29", "239". The data type for the column in SQL is varchar(10). How to solve this?
Excel seems to automatically convert cell values to numbers. Try prefixing the cell contents with a single quote in the Excel sheet prior to processing. Eg '001. If you can't trust the users to do that, use a string formatting routine to left pad the numbers with zeroes.
Something must be converting the data in the excel cell from a string to an integer. How are you performing the insert?
If a user enters 001 into Excel, it will be converted to the number 1.
If the user enters '001 into Excel, it will be saved in the cell as text.
If the cell is pre-formatted with the number format "#", then when the user enters 001 into the cell it will be entered as the text "001". The "#" number format tells Excel that the cell is a text cell and any entry (whether it looks like a number, date, time, fraction, etc...) should simply be placed in the cell as is - as a text cell.
Can you tell your users to pre-format this column with "#"? This is generally the most reliable way to handle this since the user does not have to remember to enter '001.
Maybe setting up the datatype "Text" for an Excel cell will help.
Excel is probably the culprit here. Try converting your file to CSV and see how it comes out. If the leading zeros are gone in the new CSV file, Excel is the problem.
Excel always does this, and its a nuissance. There are three workarounds I know of:
BEFORE entering the data in any cell in Excel format the cell as text (you can do a whole column if needed.) This only works if you control the spreadsheets and users, which is basically never :-).
Assume you'll get a mix of numbers and/or text in the Excel data, and fix it in Excel before import: add a column to the spreadsheet and use the TEXT() function to convert the number to text, as in =TEXT(A2, "000"); fill down. Also assumes you can edit the worksheet.
Assume you have to fix the numbers upon insert in your code. Depending on how you are loading the data, that could happen in T-SQL or in your other code. In TSQL this expression works to pad with zeros to a width of 3 characters: right( '000' + cast ( 2 as varchar(3) ), 3 )
