Formulas For System Column

ninakondza

My sheet has a system column that shows the Modified Date of each row. Is there a way for me to pull the most recent date out to the sheet summary? I tried =MAX(Modified:Modified) but it says that it is an invalid column value.

Because its a system generated column you may need to break out the date into a user column first. You can use the DATEONLY function to separate out the date, then reference the max from that column. You'll want both columns to be date formatted columns.

Hi Mike! I tried that, but it still says INVALID COLUMN VALUE when I try to find the max of the DATEONLY column.

The error is indicative of trying to get a certain type of data (DATE) in a non-date column type. Whichever column the MAX formula is in, you need to make sure that one is set as a Date Column type.

Also make sure that your Sheet Summary filed is set to be a date type field.
