data analyst/mapping friends, do any of you have a tool you rec for creating documentation of data mapping? ideally free/open source .... i'm doing okay with spreadsheets for xml -> db files, but documentation of flat files -> db has been trickier
@kate at my old job we just used excel for anything spreadsheet-based and annotation tools on PDFs for any normal files (like invoices)
@imp yeah, that's about where i'm at rn
