The think-cell datasheet does not open


The internal data sheet does not open when double-clicking a think-cell chart.


1. Reinstall think-cell

Reinstall think-cell. Please download the current think-cell version from our download web page.

2. Restart your PC

To ensure that no hidden PowerPoint or Excel processes remained stuck on your machine, disrupting normal operation, please restart your PC.

Alternatively, close all respective processes in the Windows Task Manager.

  1. Open the Windows Task Manager and check for remaining POWERPNT.EXE or EXCEL.EXE processes.
    • Windows Vista and Windows 7: Task ManagerProcesses.
    • Windows 8, Windows 8.1 and Windows 10: Task ManagerMore DetailsDetails.
  2. End these processes.

3. Check if security settings prevent think-cell from loading automatically

Open Excel. Do you see a yellow message bar below the ribbon in Excel?

Office 2016 security warning

If yes, add think-cell to the list of trusted publishers as described in KB0187.

4. Check if think-cell is running in Excel

If the think-cell group does not appear on the Insert tab of Excel's ribbon, the think-cell COM Add-In may be disabled in Excel.

Microsoft Office automatically disables add-ins that did not start successfully before. You can enable think-cell again as explained in KB0005.

5. Multiple Monitors

If you ever used multiple monitors, the datasheet window may appear on a monitor that is currently switched off or disconnected.

Switch all monitors on and open a chart's datasheet. The datasheet will appear on the monitor on which you placed it last time.


  1. open the screen resolution settings (Windows Vista and later):
    Control PanelAppearance and PersonalizationDisplayAdjust Resolution.
  2. Click Identify.
  3. Select any monitors you currently do not see and disable Extend these displays.
  4. Restart PowerPoint.

6. The internal datasheet does not open, but only some charts are affected.

Inserting a new think-cell chart, the internal datasheet opens correctly.

If you are using Microsoft PowerPoint 2010 RTM, this issue may occur with think-cell charts that were created or modified with newer Microsoft PowerPoint versions (e.g., Microsoft Office 2010 SP1 or later).

Verify your PowerPoint version:
