Is it possible to Select or Clear All sheets in one click

Is it possible to Select and Clear all Excel sheet in one click

Just write empty cells to them.

@Nick_Boyts,
My actual requirement is from the excel files dynamo read Worksheets then pop-up in List Selector. There are more than 100 Worksheets in Excel. Instead of check/Clear, I want to select all worksheets or Clear all worksheets in one single button (Select all / Clear all) Is there any to to write in python code

Ah, I understand now. Use DataShapes. The ListView selection type has toggles for both options by default.

Thankyou, its working
