LOCAL-FIRST DATA CONTROL

Find the difference before it becomes an operations problem.

Audit CSV or JSON exports for missing values and duplicate records, then reconcile two datasets by a shared key to surface missing records and field-level mismatches.

Your files stay local. This page processes selected files in your browser. It does not upload them to an Ops Control HQ backend.

DATASET QA

Audit one export

Useful before imports, reporting, handoffs, CRM cleanup, inventory review, payout reconciliation, or migration work.

CSV or JSON file Optional unique-key field

Choose a file or load the sample dataset.

TWO-FILE RECONCILIATION

Compare two exports

Choose a shared key, then see records missing from either side, duplicate keys, and cells whose values differ.

Left CSV or JSON Right CSV or JSON

Shared key

Load two files or use the sample reconciliation.

WHEN THE DATA PROBLEM IS REALLY A CONTROL PROBLEM

Turn recurring cleanup into an operating routine.

If you keep reconciling the same exports manually, the next useful step is usually ownership, cadence, exception handling, evidence, and a decision rule—not another one-off cleanup.
