hissih/sumoffice-preview repository overview

⁠SumOffice preview box

Thumbnails, HTML pages and PDF from Word and Excel files without an office suite, rendered by the same engines as the editors (SumDoc, SumSheet): correct formulas, cached values, page layout. 224 MB, fonts inside, nothing kept; honest headers say what was drawn.

docker run -d --name sumoffice-preview --restart unless-stopped -p 127.0.0.1:8099:8099 hissih/sumoffice-preview:latest
# then POST a file to /thumb, /pages or /pdf
