How to read Test.csv file format in autoit - autoit

Question

I have test.csv file need to read all the data using autoit

Answer 1

As TeamKiller said your question is quite vague but here is a sample code that should give you an idea of how to read a CSV file.
#include <GUIConstants.au3>
#include <Array.au3>
#include <File.au3>
#include <String.au3>
Opt("MustDeclareVars", 1)
Global Const $CSVFILE = "C:\Temp\test.csv"
Global Const $DELIM = ";" ;the delimiter in the CSV file
Global $i, $arrContent, $arrLine, $res = 0
$res = _FileReadToArray($CSVFILE, $arrContent)
If $res = 1 Then
For $i = 1 To $arrContent[0]
$arrLine = StringSplit($arrContent[$i], $DELIM)
If IsArray($arrLine) And $arrLine[0]<>0 Then
_ArrayDisplay($arrLine)
; do something with the elements of the line
Else
MsgBox(48, "", "Error splitting line!")
EndIf
Next
Else
MsgBox(48, "", "Error opening file!")
EndIf

return value of _ParseCSV() is 2D array like
$array[1][1] first line first data
$array[1][2] first line second data
$array[3][5] 3rd line 5th data
$array[0][0] gives number of lines
$array[0][1] gives number of data in each line
no need for includes
params:
filename
delimeter
message display if cannot open file
logical true/false to skip the first line of the file
;_ParseCSV("filename",",","message if error happens",true)
Func _ParseCSV($f,$Dchar,$error,$skip)
Local $array[500][500]
Local $line = ""
$i = 0
$file = FileOpen($f,0)
If $file = -1 Then
MsgBox(0, "Error", $error)
Return False
EndIf
;skip 1st line
If $skip Then $line = FileReadLine($file)
While 1
$i = $i + 1
Local $line = FileReadLine($file)
If #error = -1 Then ExitLoop
$row_array = StringSplit($line,$Dchar)
If $i == 1 Then $row_size = UBound($row_array)
If $row_size <> UBound($row_array) Then MsgBox(0, "Error", "Row: " & $i & " has different size ")
$row_size = UBound($row_array)
$array = _arrayAdd_2d($array,$i,$row_array,$row_size)
WEnd
FileClose($file)
$array[0][0] = $i-1 ;stores number of lines
$array[0][1] = $row_size -1 ; stores number of data in a row (data corresponding to index 0 is the number of data in a row actually that's way the -1)
Return $array
EndFunc
Func _arrayAdd_2d($array,$inwhich,$row_array,$row_size)
For $i=1 To $row_size -1 Step 1
$array[$inwhich][$i] = $row_array[$i]
Next
Return $array
EndFunc

As for parsing a CSV file, you are likely better off using a library (called user-defined functions in AutoIt), especially if you e.g. have complex CSVs with quoted strings (commas inside of the "cell"/string) or line breaks, which are hard to handle.
The best I can recommend is CSVSplit.
Basically you have a function _CSVSplit that takes a whole CSV file (content, i.e. string!) and returns you a two-dimensional array:
Local $sCSV = FileRead($sFilePath)
If #error Then ; ....
$aSplitArray = _CSVSplit($sCSV, ",")
You can then do everything you want with this array. Obviously, CSVSplit also provides the "reverse" function for turning an array into a CSV string again, _ArrayToCSV.
