FAQs
Frequently asked questions
Answered all frequently asked questions, Still confused? feel free to contact us.
What file types do you support?
You can compare XLSX and CSV files. For CSV files, the tool treats them as a single sheet (Sheet1).
How does the comparison work?
You select one or more primary key columns. We match rows using those keys and then detect missing, new, updated, and deleted records.
Can I compare multiple sheets in an Excel file?
Yes. If your XLSX has multiple sheets, you can select primary key columns for each sheet before running the comparison.
Is my data stored?
Files are used only for generating the comparison result.
