Not sure you got my mail, so I send to you in this context (menu item visible only to admins) --

1. When I tested the "big table" I got a memory error, so my tweak to PHP wasn't sufficient on the shared server. Therefore, for now, I linked that menu to the test site, where I control the memory. Also, the field data link goes there too, so that reports can be integrated into the "big table" for download.

2. The csv link at the bottom of the page is the download; it opens the selected rows in Excel.

3. No need to upload the spreadsheet, since that's a one-time thing and we never tested an export from your system.
