1. Do the headers need to match?
For best results, yes. The tool appends the second dataset to the first, assuming they share the same structure.
2. What happens to the header of the second dataset?
The tool automatically removes the first line (header) of the second dataset before merging.
3. Can I merge more than two datasets?
Currently, the tool supports merging two datasets at a time. You can merge the result with a third dataset if needed.
