This is great feedback - thank you again. It sounds like removing the thousands separator on CSV download (but leaving the decimal point, if applicable), or providing an option to remove it on CSV download, would be a great win that would satisfy most of peoples' problems. We will definitely look into doing this in the near future!
Unfortunately, there are many technical reasons why providing a scalable and maintainable XLSX export is difficult and a big lift. We are still considering it for the future, though. In the meantime, if you just want to download one table in CSV (as opposed to everything in the project), you can double-click the top-left cell of the table header (ie, above the dimension name), and it will select everything in the table. You can then right-click > Download CSV from there. We are also working on other features that hopefully should release next year that will make downloading CSV from an individual table even easier (and better).
