Make spreadsheet save in human-readable format for version control

Question

Apparently Gnumeric's native file format is compressed xml.

Diffing binary files isn't easy, so you lose many of the advantages of version control.

Is it possible to get it to save (and load) its files in straight xml (or any other human readable format)?

Answer 1

Gnumeric's preferences allow you to set a compression level of 0 which results in uncompressed files.
