Need help on excel datatable operations - SushantS - 11-19-2015

Hi

I am new to QTP. Need help on excel datatable operations.

I have 4 excel files in a folder. I need to convert all excel files to CSV.

I have written below code, but somehow it wont work. getting error message as "Open method of Workbooks class failed".

Please find below my code:


Option Explicit 
Dim TotRow,i,ExcelObj,Sourcefile,TargetFile

TotRow =  DataTable.LocalSheet.GetRowCount

For i = 1 To TotRow

    Set ExcelObj = CreateObject("Excel.Application")
    ExcelObj.DisplayAlerts = False
    ExcelObj.Visible  = False  
    
''    Sourcefile = Datatable("SourceFile",dtlocalsheet)
''    
''    TargetFile = Datatable("TargetFile",dtlocalsheet)
    
    ExcelObj.Workbooks.Open Datatable("SourceFile",dtlocalsheet)
    ExcelObj.SaveAs Datatable("TargetFile",dtlocalsheet)
    ExcelObj.Application.Quit

Next


Datatable Details:

          Sourcefile                                                [i]TargetFile[/i]

C:\QTP\ExpectedReports\a.xlsx               C:\QTP\ExpectedReports\a.csv
C:\QTP\ExpectedReports\b.xlsx               C:\QTP\ExpectedReports\b.csv
C:\QTP\ExpectedReports\c.xlsx               C:\QTP\ExpectedReports\c.csv
C:\QTP\ExpectedReports\d.xlsx               C:\QTP\ExpectedReports\d.csv


Please Note: If I provide full path of sourcefile and targetfile then code works. but I don't want to enter those each time as there are 1000 of files in a folder which I need to concert to CSV.

Thanks,
Sushant

Instead of using QTP script use vbscript

Code:
'------------------- SET SEMI-COLON DELIMITER VIA WIN REGISTERS ---------------
strDelimiter = ";"

strSystemDelimiter = ""           ' This will be used to store the current sytem value
Const HKEY_CURRENT_USER = &H80000001

' Get the current List Separator (Regional Settings) from the registry
strKeyPath = "Control Panel\International"
strValueName = "sList"
strComputer = "."
Set objRegistry = GetObject("winmgmts:\\" & strComputer & "\root\default:StdRegProv")
objRegistry.GetStringValue HKEY_CURRENT_USER, strKeyPath, strValueName, strSystemDelimiter

' Set it temporarily to our custom delimiter
objRegistry.SetStringValue HKEY_CURRENT_USER, strKeyPath, strValueName, strDelimiter


'----------------------------- CONVERT XLS TO CSV ------------------------------
Dim strExcelFileName
Dim strCSVFileName
Dim objFSO
Set objFSO = CreateObject("scripting.filesystemobject")  
strPath = objFSO.GetAbsolutePathName(Wscript.Arguments.Item(1))

strExcelFileName = WScript.Arguments.Item(0)  'file name to parses

rem get path where script is running
Set fso = CreateObject ("Scripting.FileSystemObject")  'use this to find current path
strScript = Wscript.ScriptFullName
strScriptPath = fso.GetAbsolutePathName(strScript & "\..")

rem If the Input file is NOT qualified with a path, default the current path
LPosition = InStrRev(strExcelFileName, "\")
if LPosition = 0 Then 'no folder path
strExcelFileName = strScriptPath & "\" & strExcelFileName
strScriptPath = strScriptPath & "\"
else                 'there is a folder path, use it for the output folder path also
strScriptPath = Mid(strExcelFileName, 1, LPosition)
End If
rem msgbox LPosition & " - " & strExcelFileName & " - " & strScriptPath  ' use this for debugging

Dim objXL
Dim objWorkBook, local
Set objXL = CreateObject("Excel.Application")
Set objWorkBook = objXL.Workbooks.Open(strExcelFileName)

objXL.DisplayAlerts = False
rem loop over worksheets
  For Each sheet In objWorkBook.Sheets
      'only saveAS sheets that are NOT empty
if objXL.Application.WorksheetFunction.CountA(sheet.Cells) <> 0 Then
rem             sheet.Rows(1).delete  ' this will remove Row 1 or the header Row
local = true  
call objWorkBook.SaveAs(strPath & "\" & sheet.Name & ".csv", 6, 0, 0, 0, 0, 0, 0, 0, 0, 0, local)
    End If
  Next

rem clean up
objWorkBook.Close
objXL.quit
Set objXL = Nothing
Set objWorkBook = Nothing
Set fso = Nothing

'------------------------- RETURN REGISTRY CHANGES BACK --------------------
' Reset the system setting to its original value
objRegistry.SetStringValue HKEY_CURRENT_USER, strKeyPath, strValueName, strSystemDelimiter

rem end script
