Frequently asked questions
What JSON shape works?
An array of flat objects: [{name, age}, {name, age}]. Nested objects are flattened with dot notation (address.city).
How are commas and quotes in values handled?
Values containing commas, quotes, or newlines are wrapped in double quotes with internal quotes escaped as "" per RFC 4180.
What if objects have different keys?
The header is the union of all keys. Missing values become empty cells.
Is my JSON uploaded?
No. All conversion happens in your browser.
