I have to convert .xls or .xlxs file to .csv file without using plugins or tools using Unix Command
Is their any way to do this ?
I Tried to do like this below ...But not working
Change the characterSet code from .xls file to UTF-8 encoding
Then create file again with extension change
cp temp.xls temp.csv
It is possible, but you need to realise that an *.xls file is a zipped directory structure (just unzip such a file, using Winzip or 7-zip). The unzipping can also be done using UNIX commands.
But what then? The directory structure is quite complicated to understand, and in order to create a script or a program which can do this (without using any external tools) is a tremendous work, so I'd propose you, either to use external tools anyway, or to make sure the files you receive already are CSV format.
mission on online course:
Download this RData file to your working directory. Then load the data into R with the following command:
load("skew.RData")
so I have downloaded it to my computer but where is my working directory? or how do I load the downloaded file to Rstudio
You can see your working directory by executing getwd().
In order to load the data you need to change it to the folder path where the data is stored.
setwd("C:/your/path")
load("skew.RData")
You can set you working directory in RStudio on the right side manually and then save the files there and open them like :
load("skew.RData")
If your file is saved somewhere else, you should define the path to it:
load("path/to/your/file/skew.RData")

I want to know how can we convert .xlsx file residing in hdfs to .csv file using R script.
I tried using XLConnect and xlsx packages, but its giving me error 'file not found'.I am providing HDFS location as input in the R script using the above packages.I am able to read .csv files from hdfs using R script (read.csv()).
Do I need to install any new packages for reading .xlsx present in hdfs .
sharing the code i used:
library(XLConnect)
d1=readWorksheetFromFile(file='hadoop fs -cat hdfs://............../filename.xlsx', sheet=1)
"Error: FileNotFoundException (Java): File 'filename.xlsx' could not be found - you may specify to automatically create the file if not existing."
I am sure the file is present in the specified location.
Hope my question is clear. Please suggest a method to resolve it.
Thanks in Advance!
hadoop fs isn't a file, but a command that copies a file from HDFS to your local filesystem. Run this command from outside R (or from inside it using system), and then open the spreadsheet.
I've been using LinqToExcel to parse an exel document for a while and suddenly it's stoped working.
I'm getting the following error:
External table is not in the expected format.
Any ideas why this is happening? Or how to fix?
if (File.Exists(filenameFull))
{
var excel = new ExcelQueryFactory(filenameFull);
IList<Row> scanningRangesRows =
excel.Worksheet("B - Scanning Ranges").ToList();
I was using version LinqToExcel 1.6.3, when the problem started happening I updated to the latest version LinqToExcel 1.6.6 to no avail.
I've just noticed that the file I'm downloading is significantly smaller than previous verisons. I opened it in notepad and I can see [Content_Types].xml amongst the binary data. So it appears that the data source is now being saved as an xml represention of the xls file with the same extension. When I open the same file manually in Excel it popup with
The file you are trying to open '', is in a different format
than specified by the file extension. Verify that the file is from a
trusted source before opening the file. Do you want to open the file
now?
On clicking yes the file still opens and looks the same as previous versions.
It's probably something to do with the file.
Maybe it's being saved as an .xlsx type of file. Can you try renaming the file extenstion to .xlsx and see if that works.
