Open the spreadsheets and documents attached to issues in a real engine and save them back. The plugin makes Redmine a WOPI host — CheckFileInfo, GetFile, PutFile and locking, with signed tokens whose signature is checked on every request. Macros, defined names, queries and pictures come back byte for byte. The editors run in your own Docker; the files never leave your servers.

Installation notes

The plugin sources live in the `integrations` branch of the repository, in `integrations/redmine/sumoffice_wopi`.

1. Copy that directory into your Redmine `plugins/` directory, keeping the name `sumoffice_wopi`.
2. Restart Redmine.
3. In Administration > Plugins > SumOffice, set the WOPI discovery URL of your SumOffice server and leave signature verification enabled.

Requires a running SumOffice server (SumSheet for .xlsx/.xlsm/.xlsb, SumDoc for .docx).
