Up to now I enter receipts by hand into a spreadsheet and cross-reference everything to my bank statements. Is there a Linux program that’ll let me download a bank statement and then intelligently categorize different entries on my bank statement? Or allow me to manually categorize entries? No spyware or intrusive software.
You should be able to do all that stuff with spreadsheets. Any program you use will be a spreadsheet under the hood anyhow.
Indeed, came to add spreadsheets, e.g. LibreOffice Calc or OnlyOffice on NextCloud if you want it Web based. If it’s “good enough” to manage the budget of countries, huge corporations, etc and is taught in schools, it’s probably good enough for a household.
