How to paste an SEC EDGAR, Google Sheet, or OneDrive link

SEC EDGAR (any of these work — the app extracts the CIK and pulls the XBRL company facts):

Filing list URL: https://www.sec.gov/cgi-bin/browse-edgar?action=getcompany&CIK=0000320193&type=10-K
Filing index URL: https://www.sec.gov/Archives/edgar/data/320193/000032019324000123/
Direct XBRL API URL: https://data.sec.gov/api/xbrl/companyfacts/CIK0000320193.json
Just a CIK number: 320193

The app maps standard us-gaap XBRL tags into income / cash flow / balance sheet sheets and populates the Period dropdown with the available fiscal years. Subtotals come straight from the filer, so the balance sheet ties exactly.

Google Sheets: File → Share → Publish to web → choose .xlsx. Paste that URL.
(View-only "Anyone with link" URLs also work — paste the normal share link and the app will convert it to the export endpoint.)

OneDrive / Office 365: Share → Anyone with the link can view, copy the link, paste here. The app appends &download=1.

If a fetch fails due to browser CORS, download the file and use the upload box instead.

Tip: Sankey rendering requires positive flows. Net losses and negative items are shown by absolute value and color.
