Frequently asked questions

What JSON shape does it expect?

An array of objects, where each object is a row and its keys are the columns.

What if objects have different keys?

The tool builds columns from the keys it finds; missing values are left blank for rows that don't have them.

Is my data private?

Yes. The conversion happens entirely in your browser.
