I made a spreadsheet to share with a colleague, featuring some checkboxes, and they complained that the checkboxes weren't working. But they were working fine for me. I figured out that I was using desktop Excel, and they were accessing the sheet via Excel online (Microsoft 365).
Minimal working example:
- Excel online > New workbook
- Cell A1 > Insert > Checkbox
- Cell B1 >
=A1 - Toggle the checkbox. B1 flickers to
TRUEand then immediately back toFALSE. - Open the workbook in the Excel desktop app - cell B1 shows
TRUE/FALSEcorrectly (whether you toggle the checkbox in the browser or the app).
Same behaviour in Firefox, Edge, and Chrome. Any thoughts?
