Insert large data in excel cell

11 posts in this topic

I'm using excel udf to write some data in specific cells. Unfortunately I have to put there images also and here the problems starts. I'm not necessarily interested to see the images in excel so I encode them base64 but data leght is far too much for an excel cell, whici is limited to 32,767 characters. What alternatives I have?

Write them as shapes to a sheet and then hide this sheet.

Will this work well if I have 20000 rows and for each row I have 3 images? Maybe the most normal method would be to split data in chunks of 32,767 characters and write them in multiple cells. Of course it's not pretty but may work. I'm still open to any suggestion.

Shapes aren't related to cells. I understand it as they are placed on another layer. You can place them wherever you like on the sheet.

I have never done this myself but I would try the following:

Place the image on another worksheet. To make it invisible you can either set the image to visible=False or the whole worksheet

Set the name of the image like "row-column" so you have a connection between a cell and an image.

You can access each image by using this name.

If you like I can post an example.

Example:

$sFile = @ScriptDir & "\test.jpg"
Global $oExcel = ObjCreate("Excel.Application")
$oExcel.Visible = True
$oWorkbook = $oExcel.Workbooks.Add()
$oExcel.Sheets.Add()
$oWorksheet = $oWorkbook.Sheets(2)
$oPicture = $oWorksheet.Shapes.AddPicture($sFile, -1, -1, 1, 1, 0, 0)
$oPicture.Scalewidth(1, -1, 0)
$oPicture.Scaleheight(1, -1, 0)
$oPicture.Visible = False
$oPicture.Name = "001-003" ; Example for: Row 1, column 3
MsgBox(0, "", "Press enter to set visibility to true")
$oWorksheet.Shapes.Item("001-003").Visible = True
$oExcel.Close
Exit

Sets the size of the picture

Makes the picture invisible

Adds a name ("Row-Column") to the picture

Accesses the picture by name ("Row-Column") and makes it visible.

Thank you! That's pretty cool, just one more question. Could I insert the image from binary data? If this is not possible it's not a big deal to write in temporary files the images before to insert them in excel.

I don't think so because the Add method requires a filename.

      I'm trying to insert the following formula in cell A2 using my script:
      =if(A1=""; "YES"; "NO")
      To my understanding, the line of code should be similar to this:
      _Excel_RangeWrite($MasterFile, Default, "=if(A1=""; "YES"; "NO")", "A2")
      However, it does not work, probably due to the multiple quotation marks that confuse the script :C
      How do I avoid this problem?

      Hi everybody,
      i have a question about Excel, i have to create several charts one below the other dynamically.
      I have thought to use:
       
      $oRangeLast = .UsedRange.SpecialCells($xlCellTypeLastCell) $iRowCount = .Range(.Cells(1, 1), .Cells($oRangeLast.Row, $oRangeLast.Column)).Rows.Count  
      And then to use it in this way:
      $Graph_position = "=Test1!A"&$iRowCount+2&":K"&$iRowCount+24 But it doesn't work with charts.
      Does anyone have a suggestion?

      I want to automate the process "get external data" in Excel, i want to import the data from the text file and basically create a csv file with a specific character encoding.
      Is it possible with AutoIT?

      Hi,
      since some days I become this error message exiting my app:

      Eventviewer shows following data:

EndIf EndFunc Do following steps to prove:
      - start app
      - click "next" on main gui
      - wait minimum 5 seconds (until the arrows left and right on "gui left" disappear)
      - close gui left or right
      - close main gui
      - look on console written "EXIT" the last code line before exit
      - now windows error message above appears
      The funny thing is if I don't wait the 5 seconds (before the half transparent arrows disappear) closing the gui then I will get no win error message.
      If I comment _AcrobatShow() out then the error never appears. So it seemed to be an acrobat reader issue. Every week at work there are a lot of updates, but there is no chance to know which one. But since one update this error happens.
      Any solutions? Regards, Conrad
