I'm trying to clear all the values from a Google Sheets sheet, while keeping the formatting and data validation (e.g. dropdowns and checkboxes). The documentation for the spreadsheets.values.clear API method says,
Only values are cleared -- all other properties of the cell (such as formatting, data validation, etc..) are kept.
However, when I run this method, the data validations I have set up on the sheet are deleted.
I suppose I'm both trying to report a bug (the support website directs me to StackOverflow), and also soliciting any suggestions for how I might accomplish the "clear all values but leave formatting and data validation" task.
