I wonder if a spreadsheet and its editor could go in a self-contained HTML file. You'd open it in a browser, it modifies its own source code, and you just re-export or "Save Page As" when you're done?

Furthermore, maybe the data could be in CSV at the top of the file, in an HTML comment, and the editor could be in HTML at the bottom of the file, in a CSV comment, so the file could be opened in either a browser or Excel? Haha

Possibly! Discussed this a little here: https://twitter.com/meshspreadsheet/status/10554309994530529...

Programatically invoking the "Save As" dialog seems troublesome. Maybe there could be a signed WebExtension blob in the file, too - or it should download the latest updated library script every time the file is opened (although then there are security & CORS issues).
