Frequently Asked Questions

Does it upload data?

No.

What JSON works best?

An array of objects with scalar values.

Preparing JSON for a spreadsheet

This tool works best with an array of flat objects, where every object has the same keys. Nested objects and arrays do not fit neatly into columns, so flatten them first.

Open the CSV in a spreadsheet and check dates and long numbers, which some programs reformat automatically. Values containing commas or quotes are escaped for you.
