Local data comparison for Windows
Windows desktop softwareDataPreflight is Windows desktop software for comparing two tabular data files before import, analysis or handoff. Files are processed locally on your computer.
Lite is free. Standard is a one-time purchase for one Windows computer.
01 / Product overview
DataPreflight compares two CSV, TSV, XLSX or XLSM data files. You choose the record key and fields to compare, then review matches, value differences and records found on only one side.
The comparison runs on the Windows computer. DataPreflight does not upload the source-file contents or send telemetry. This website provides product information and does not accept data-file uploads.
Both editions produce an HTML report and CSV differences. Standard also produces structured JSON evidence and an XLSX audit workbook, and includes managed profiles and batch reporting.
02 / Intended uses
DataPreflight is intended for people and small teams who need to compare tabular business data before the next processing step.
Compare current and incoming data before loading it into another application or business system.
Identify changed or missing records before reporting, aggregation or analysis.
Create reviewable output before passing data to a colleague or another workflow.
A comparison does not guarantee that data is complete, correct or suitable for every downstream use. Results require review in the context of your own workflow.
