What formats would you like besides CSV, TSV, and JSON?

Oh, and one more example: I wanted to find the number of active users for all projects per language and find most active languages per region. Once again, straightforward if you can download data (sum of few tables plus regions from https://stats.wikimedia.org/EN/Sitemap.htm ), but hardly possible without downloading option.
We are not Google who hides trends data and shows only relative graphs for Google Trends. Please make data available for download like one could easily copy old tables. Or keep old tables (no matter they are ugly, having data is essential).
It is important, specially for research purposes and comparative studies.
Let me testify that this feature was asked a lot for Wikistats 1.0 and I mean really a lot. Many people wanted to play with data themselves. Sadly it never happened, as it would either complicate the code further or require a major rewrite. Wikistats 1.0 does data aggregation and presentation in one go (not a lucky choice), so code is already interspersed with output statements. Writing a flat csv file besides a not quite flat html table would make the code even harder to maintain.
