Question 1

How do I merge multiple CSV files?

Accepted Answer

Drag and drop your CSV files into FileNaut. The tool auto-detects headers, aligns matching columns, and combines all rows into a single downloadable CSV file.

Question 2

Do the CSV files need the same columns?

Accepted Answer

No. FileNaut handles mismatched columns by creating a unified header row. Missing values are left empty in the merged output.

Question 3

Is there a limit on the number of files?

Accepted Answer

There is no hard limit. You can merge as many CSV files as your browser can handle. All processing happens locally on your device.
