Load a Spreadsheet Input Manifest for a run, see the ranges to recompute in Excel, paste each one back, and get a receipt naming every cell that matches or diverges. Reuses the workbook engine's own CSV parser and range digest, so a match here means the exact same canonicalization and hash the manifest was built from.

The incumbent this replaces: recompute in Excel, paste back. No macro, no shared drive round-trip. This tool intakes CSV or a plain pasted range only, the same strict RFC 4180 parser the workbook editor uses. It never opens or parses an xlsx file.
1Load the run's manifest
Paste the Spreadsheet Input Manifest exported for the run you're verifying (the source csv digest plus one values_digest per range). This names what to open and recompute in Excel: the source data behind each listed range.
2Paste back from Excel
Recompute each range below in Excel using the source data named by the manifest, then paste the result back exactly as it appears in the sheet (comma or tab separated, no headers). The optional expected column lets you also paste in a Power Query export of the same range, which turns a mismatch into a per-cell diff instead of a whole-range one.
