Frequently asked questions
What JSON can I convert?
Use a nonempty array of objects. Columns are the union of keys; missing fields and null become empty cells. Nested objects become JSON text inside a cell.
How are commas, quotes and formulas handled?
Cells containing commas, quotes or line breaks are quoted, with internal quotes doubled. Strings starting with =, +, - or @, even after whitespace, get a leading apostrophe to reduce spreadsheet formula execution. Review the file in its destination.
