Data validation

ONLYOFFICE Spreadsheet Editor offers a data validation feature that controls the parameters of the information entered in cells by users.

To access the data validation feature, choose a cell, a range of cells, or a whole spreadsheet you want to apply the feature to, open the Data tab, and click the Data Validation icon on the top toolbar. The opened Data Validation window contains three tabs: Settings, Input Message, and Error Alert.

Settings

The Settings section allows you to specify the type of data that can be entered:

Note: Check the Apply these changes to all other cells with the same settings box to use the same settings to the selected range of cells or a whole worksheet.
