Frequently asked questions

What if files have different columns?

All columns are included. Rows from files without a column get an empty cell.

How many files can I merge?

As many as your device can hold in memory, usually hundreds of files.

Are my files uploaded?

No. Files are read and processed by your browser on your own device, so there is no upload wait and no size limit set by a server.
