What it reads and where files come from
Sprites reads PDFs, Word documents, spreadsheets in Excel, Numbers and CSV formats, and Google Docs and Sheets shared from Drive. OneDrive files come through the same connection pattern. Multi-tab spreadsheets are ingested per tab, so you can ask about "the Q2 tab" or filter rows the way you would in a sheet. Large documents are read in full rather than sampled, and answers cite where in the document the evidence came from.
