FAQ

What happens to existing data after I set a column type?

Existing data is displayed and checked according to the new column type rules.
For example, if you change a text column to a date type, values that can be recognized as dates are shown in a date format.
Content that does not match the preset restriction stays in place and is marked as not matching the preset rule.

Right-click the target column header and open the Column Type submenu.
Select the Dropdown List type.
In the settings panel that opens, add or adjust the option values and complete the setup.

What is the purpose of setting the starting row?

Setting the starting row controls which row the column type starts from.
When the default is row 2, row 1 can usually stay as the header row.
If the first few rows are used for titles, notes, or data that should not be formatted, set a later row number.
