Frequently Asked Questions
How do I merge multiple CSV files into one?
Upload all the CSV files, confirm they share the same columns, and the tool stacks the rows into a single downloadable CSV.
What if my CSV files have different columns?
For a clean merge the headers should match. If columns differ, align them first or the extra columns may be left blank.
Does the merger remove the repeated header rows?
Yes, you can choose to keep only the first header so the merged file does not repeat column names between files.
