Those filters do not apparently function in spreadsheets other than actual Excel, which is often not owned by people like me who have no reason to invest in the MS pro suite. In LibreOffice (open source) I get this error "Ranges containing merged cells can only be sorted without formats." I managed to get them to sort in Google Sheets, but not by those filters. So I need to download the files, then upload them to google!

Government agencies should not publish data in proprietary formats. Jersey City distributed a sheet about boiler inspections in a Word doc instead of a PDF! Yes, I know PDF is originally Adobe, but at this point there's many readers/writers and I've never had a problem with it. Word often has problems with interoperability, as apparently does Excel.

But, to get back to your inquiry as to why focus on teachers rather than bloated admin staff and salaries: teacher are 56% of the overall budget while admin is 8%. I shouldn't need to tell a CPA to follow the money!

Have you ever taken a look at the JCPS "user friendly budget"? I did. I found line item terms that Google couldn't define!
