Data validation for time input in Google Sheets
I am searching for a solution that would allow users to insert time values only in this format: hh:mm, and reject if something else is inserted. Something similar like data validation for date - Data validation -> Is valid date -> Reject input.
I tried to search and adjust a Regexmatch formula for this one, with no success, but I am open for other suggestions also.
Thank you in advance!
Solution
SUGGESTION
Perhaps you can try using a more specific regex such as the one sample from this existing post. Then, apply it your data validation via a custom function using REGEXMATCH function as seen here:
=REGEXMATCH(TO_TEXT(A1),"^([0-1]?[0-9]|2[0-3]):[0-5][0-9]$")
Sample Data Validation Config:
