Reduce and compress Excel documents (.xls, .xlsx, .xlsm, .ods) online
to make them smaller, so you can better send them via email.
You just need to select the Excel file (~50MB) you want to compress.
I notice you’ve mentioned "amershamhealty-us com" — it looks like a possible misspelling of “Amersham Health” (a former medical imaging company) or a website name that might be inactive or suspicious.
