Local CSV / Excel cleaning for accounting.
One tool. Three workflows.

DataTools is a desktop app that fixes the export headaches that throw off your books — the transaction your bank posted twice, the vendor entered three ways at 1099 time, the invoice your aging report counted twice. One $49 download. Mac, Windows, and Linux. Your data never leaves your computer.

📒 Bookkeeper

Bank reconciliation with an audit trail

When the Jan and Feb exports overlap, the same payment posts twice in two formats. DataTools standardizes every date and amount, then dedups on the real transaction so it ties out — with a row-level audit log to hand the client.

  • · Catch month-overlap re-import duplicates
  • · ISO dates, numeric amounts, parens-negatives resolved
  • · Hand-off-ready audit trail
  • · Sample: 26 rows → 20, six phantom duplicates removed

🧾 Accounts payable / 1099

Clean 1099 vendor list — missing EINs filled in

The same vendor entered three times, each record holding only part of the details. DataTools consolidates each vendor to one row and backfills the gaps from the duplicates, so the EINs you need at filing time are recovered.

  • · Consolidate vendor masters for 1099-NEC
  • · Recover EINs scattered across duplicate records
  • · Standardize phones, emails, and amounts
  • · Sample: 24 records → 8 vendors, 7 EINs recovered

💵 Accounts receivable

AR aging without the double-counted invoices

Double-entered invoices inflate your aging report and your follow-ups. DataTools standardizes invoice dates, due dates, and amounts, lowercases client emails, then removes the duplicate invoice numbers so the aging is accurate.

  • · Remove double-entered invoices from the aging
  • · ISO dates, numeric amounts, lowercased client emails
  • · Backfill a blank status from its twin row
  • · Sample: 26 rows → 21, five duplicate invoices removed
