hissih/sumsheet-webhost repository overview

⁠SumSheet web host

A browser editor over the SumSheet engine (Rust, no LibreOffice or Office inside). An .xlsm goes in with its VBA project, gets edited, comes out with vbaProject.bin byte-identical, and Excel opens it without a repair dialog. Power Query definitions travel with the file. A 400k-formula workbook opens in about 0.1 s.

⁠Run

docker run -d -p 8150:8150 hissih/sumsheet-webhost

Open http://localhost:8150/⁠ . One process per open document.

⁠Nextcloud (WOPI)

Works as a WOPI server through the standard Nextcloud Office (richdocuments) app, together with hissih/sumdoc-webhost for documents. Three steps, compose file and nginx config: https://sumoffice.com/nextcloud⁠

⁠Scope today
