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.

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
