Frequently asked questions

Is the data structure preserved during conversion?

Yes — rows and columns carry over as-is; for JSON, each table row becomes its own object.

Can I preview the data before downloading the result?

Yes, the tool shows a preview of the table after you upload the file, before conversion.
