spreadsheet editing in a web browser
Could anyone recommend any software for online spreadsheet editing? Obviously, google docs come to mind but it'd rather not use google or any other external hosting. I don't think we really need a fully fledged document management system. It's just for a couple of spreadsheets that need to be updated on a regular basis by people outside of the office. The features I'd like it to have are:
- password protection
- ability to edit a spreadsheet in a browser and export to .xls
- can be hosted on our server
I've been googling for some solutions but thought that, in the meantime, I could ask if any of you can recommend something that you've used and are happy with.
