That's github based for collaboration I think. The one mentioned in the post VersionXL [1] is based on the cloud version of TerminusDB (co-founder here), which is an open source revision control database. It uses delta encoding for updates, but is a proper DB optimized for the task. You get transaction processing and updates to an immutable database with version control features: branch, merge, rollback, searchable diffs, and time-travel. It also ships with a mature python client to allow you to manipulate the Excel data.
