Hi, I got a spreadsheet named 01 on OneDrive.

I created a checkbox in column G, and I would like to add a timestamp in column K when the checkbox is checked. When the timestamp is removed when the box is unticked.

I tried a few examples from Google search and YouTube, but they didn't work.
I also tried to make it in Excel, then uploaded it back to OneDrive, but the function didn't work.
Any easy solution? Thank you
