Fit rows to the columns you choose
ColumnFit is a Google Sheets add-on that resizes every row to fit the wrapped text of the columns you select, ignoring the height demands of all other columns. Google Sheets has no per-column auto-fit, so ColumnFit estimates line counts from font metrics and column width and sets row heights to match.
How to use: select one or more columns, then open Extensions → ColumnFit → Fit rows to selected columns. Make sure those columns use Wrap text.
