Sheetlot
Merge multi-broker trade CSVs
The product is the download: one file, one schema, broker column, plus flags when the same symbol trades close together across accounts.

The problem
Excel can rename columns once—until the next broker changes a header. Multi-account traders rebuild the merge every month.

Sheetlot is not a TurboTax importer and not tax advice. Official 1099-B feeds remain the filing source of truth.
