Frequently asked questions
What YAML shape is expected?+
A top-level YAML list (array) of objects. Each list item becomes a row and each key becomes a column.

Nested objects and arrays inside a value are serialised to compact JSON so the data is preserved in a single cell.
Is it free to use?+
Yes — it is completely free with no sign-up, no account and no usage limits. There is no watermark and no paywall, so you can process as many files as you like.
Is my data private and secure?+
Yes. This tool runs entirely in your browser using client-side JavaScript — your data is never uploaded to a server, stored or logged. Once the page has loaded you can even use it offline, which makes it safe for confidential or proprietary files.
