Proposal

First of all, thank you very much for your great work. Have you considered adding an export option for the ODS file format? ODS is an open ISO standard for tables that is becoming increasingly common in the EU. For example, Germany has made open document formats (including ODS) mandatory. This means that government administrations and offices will require data to be submitted in an open standard format. ODFs are fully documented and presumably a more straightforward implementation than OpenXML (Microsoft). It would be fantastic if you could consider adding an export option.
