The Spreadsheet application in CryptPad is an integration of OnlyOffice. To read more about the details of this integration see What is the relationship between CryptPad and OnlyOffice?.
CryptPad integrates OnlyOffice spreadsheets into the same encrypted collaboration system as the other applications. Additionally OnlyOffice provides a wide range of functions in a tabbed toolbar. This results in a double toolbar that can cause confusion:
The topmost CryptPad toolbar is used for File operations (including import/export, history, properties, etc) as well as Share and Access.
The OnlyOffice toolbar is used for all functionality within the spreadsheet document itself, as well as the collaboration modes explained in the next section.
Undo and collaboration modes¶
OnlyOffice provides two collaborative editing modes in spreadsheets that affect how changes are synced between users and whether or not the Undo functionality is available.
Fast Mode is enabled by default. New edits by all users are automatically synced with others as they are made. In this mode it is not possible to undo.
Strict Mode allows each user to make changes independently. The modified cells are "locked" for others until the author manually saves their changes. New edits are only synced with other users after being saved. In this mode it is possible to undo changes that have not yet been saved. When a user saves their changes, others are prompted to save in order to receive the latest edits.
Ctrl Z is pressed for undo, the application will automatically suggest switching to Strict Mode to enable the undo functionality.
To switch back to Fast mode use the Collaboration tab in the OnlyOffice toolbar and select Co-editing Mode > Fast.
CryptPad remembers your choice of editing mode on each device for all documents.
To access the spreadsheet history, use File > History in the CryptPad toolbar.
Due to the integration of OnlyOffice with CryptPad's encrypted real-time collaboration, history in speadsheets works differently than in the other applications.
History in spreadsheets only allows to jump back to the previous version, and then move forward through individual edits.

To print spreadsheets it is recommended to export using one of the formats below and to handle page layout with a desktop application such as LibreOffice Calc.
