Why use _Excel_RangeRead in a loop - that takes forever.

Use the function with default values and it will return an array with all used cells.

The function page says that _Excel_RangeRead returns the data from the specified cell(s). A string for a cell, a zero-based array for a range of cells. Cant you use ubound with the returned array?

untested guess:

$data = _Excel_RangedRead($oWorkbook, Default, "A1")
For $i = 2 to ubound($data) - 1

According to the help file:

"$vRange [optional] Either a range object or an A1 range. If set to Default all used cells will be processed (default = keyword Default)"

If IsArray($data) Then
    If UBound($data, 0) = 2 Then ; 2D-array
        For $i = 0 To UBound($data, 1) - 1
            ; process first column of the returned 2D-array: $data[$i][0]
        Next
    Else
        For $i = 0 To UBound($data, 1) - 1
            ; process first column of the returned 2D-array: $data[$i]
        Next
    EndIf
EndIf

@water & @

computergroove, I have a workbook and it contains data in F2 to F22. Now, I need to read that data. But next time, my program has no idea about what is the upper limit. Now it is F22. But next time it will be F34 or F56 or something like that. Then how can i find it without a loop. And with this code, i only get one cell value. Not an array
$Result = _Excel_RangeRead($WBook, "Sheet2", "F2")

As I stated above. Try:

$Result = _Excel_RangeRead($WBook, "Sheet2")

@water, it will give all the data in that sheet. I think that will slow down my program a bit. Am i right ?

Only a bit. But $WBook.ActiveSheet.Usedrange.Columns is faster, no doubt.

      HI there
      this is driving me nuts - i get the row count, but not the column count - what am I missing? Thanks for your help!
      #include <Excel.au3> #include <Array.au3> #include <MsgBoxConstants.au3> ; XlDirection enumeration: https://msdn.microsoft.com/en-us/library/office/ff820880.aspxGlobal $oExcel = _Excel_Open() Global $xlup = -4162 Global $xlByRows, $xlPrevious, $xlByColumns Global $oExcel = _Excel_Open() $bookname = "temp.xlsx" $sWorkbook = @ScriptDir & "\" & $bookname Global $oWorkbook = _Excel_BookOpen($oExcel, $sWorkbook, Default, Default, True) With $oWorkbook.ActiveSheet ; process active sheet $oRangeLast = .UsedRange.SpecialCells($xlCellTypeLastCell) ; get a Range that contains the last used cells $iRowCount = .Range(.Cells(1, 1), .Cells($oRangeLast.Row, $oRangeLast.Column)).Rows.Count ; get the the row count for the range starting in row/column 1 and ending at the last used row/column $iColCount = .Range(.Cells(1, 1), .Cells($oRangeLast.Row, $oRangeLast.Column)).Column.Count MsgBox(0, "", "row:" & $iRowCount & "Col:" & $iColCount) EndWith  
      for context - i want to :
      * count columns used in excel
      * create ini file from the rows in each column - finishing at the last column used - i.e. one column for one ini file; containing 15 rows or so.
      is it better to read the entire sheet to an array via the sheettoarray function? then read it from that?

      Sorry if this is a repost, but having some trouble searching for the answer and pretty tired right now.
      I'm just wondering how to make a border around a range of cells in Excel. I want the regular lines created by selecting "All Borders" option around F2:G3
      I saw this code:
      With $oExcel.ActiveSheet.range("F2:G3") .Select .Borders($xlEdgeBottom).LineStyle = $xlContinuous .Borders($xlEdgeBottom).Weight = $xlThick .Borders($xlEdgeBottom).ColorIndex = $xlAutomatic EndWith but I get errors of these variables not existing. It seems these no longer exist in the "#include <Excel.au3>"
      Is there another include file I need?
      I got this to work for highlighting cells, wondering if there is a option similar to this for all borders?
      $oExcel.ActiveSheet.Range("F2:G3").Interior.ColorIndex = 6 Thanks

      I am working on a script that will turn all file names in a directory into an array, and then writes this Array to an Excel file.
      This in itself is working, but the RangeWrite function always puts the Array count in the first cell.
      How can i make sure this does not happen? I can of course just filter it out in Excel, but i am trying to keep all logic of filtering text in my script.
      This is what my script looks like:
      Local $Yesterday = _DateAdd('d', -1, _NowCalcDate())
      Local $cDate = StringReplace($Yesterday, "/", "-")
      Local $aFileList = _FileListToArray(@WorkingDir & "/" & $cDate, "*")
      Local $oExcel = _Excel_Open()
      Local $oWorkbook = _Excel_BookNew($oExcel)
      _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $aFileList)

      Hello,
      Is there a way wherein I can access the data from an array coming from an Excel file then have it assigned on to a variable?
      Below is a snippet of my current code. For now, it just reads and outputs the data from the excel file and have it displayed via an array.
      #include <Array.au3> #include <Excel.au3> #include <MsgBoxConstants.au3> Local $oExcel = _Excel_Open(False) If @error Then Exit MsgBox(0, "Error", "Error creating application object." & @CRLF & "Error: " & @error & " Extends: " & @extended) ; Open Excel Woorkbook and return object Local $sWorkbook = @ScriptDir & "\Excel Files\Test Data.xlsx" Local $oWorkbook = _Excel_BookOpen($oExcel, $sWorkbook, False, True) If @error Then MsgBox(0, "Error", "Error opening workbook'" & $sWorkbook & ".'" & @CRLF & "Error: " & @error & "Extends: " & @extended) _Excel_Close($oExcel) Exit EndIf Local $aResult = _Excel_RangeRead($oWorkbook) ; Error Trapping If @error Then MsgBox(0, "Error", "Error reading data from '" & $sWorkbook & ".'" & @CRLF & "Error: " & @error & " Extends: " & @extended) _Excel_Close($oExcel) Exit EndIf _ArrayDisplay($aResult) My Excel file has values from Column A to H with values from 1 to 30, what I desired to do is have the value in "A7" assigned on to a variable. 
       
      Any help is appreciated. Thanks in advance.

      I am trying to close an excel file that was not opened with _Excel_Open.  How do I found the excel application object?  I'm new and I am used to files and folders names, so an 'object' is new to me.  I have the info too and simply spy, but I don't know which info is the object name/string.  In the example from help doc's I see the code below and I tried justin pasting it into Scite.
      <
      Local $oExcel1 = ObjCreate("Excel.Application")
      ; Close the Excel instance which was not opened by _Excel_Open
      ; (will still be running because it was not opened by _Excel_Open)
      _Excel_Close($oExcel1)
      If @error Then Exit MsgBox($MB_SYSTEMMODAL, "Excel UDF: _Excel_Close Example 1", "Error closing the Excel application." & @CRLF & "@error = " & @error & ", @extended = " & @extended)
      Sleep(2000)
      Local $aProcesses = ProcessList("Excel.exe")
      MsgBox($MB_SYSTEMMODAL, "Excel UDF: _Excel_Close Example 1", "Function ended successfully." & @CRLF & @CRLF & $aProcesses[0][0] & " Excel instance(s) still running.")
