Frequently asked questions
Is the header repeated in each file?
Yes, by default, so every part can be imported on its own.
Can I make one file per state or branch?
Yes. Choose “By column value” and pick that column.
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.
