Privacy details

CSV to YAML converter processes your input in this browser. Inputs and results are excluded from analytics. Recent tools save tool names, visit counts and last-visit times. Saved tools store only their names. Draft saving is optional and stays on this device; delete saved text with the draft controls. Loading text from a URL is optional and contacts that server; its URL and your IP address are visible to the server. An optional “Use in” action keeps a handoff in this tab. The next tool removes it on arrival and ignores it if more than a minute has passed.

Copy link includes the inputs you choose to share in the address. Anyone with that link can reopen them. Files and generated results are excluded. Password and key tools share settings only.

CSV to YAML converter explained

CSV to YAML converter reads a header row and preserves each following cell as text. The result uses a YAML sequence of mappings, quoting number-like text so its type stays a string.

A worked example

The CSV value 008 becomes a quoted YAML string, not the number 8. A comma inside a quoted cell stays within that cell.

Before you use the result

Quoted fields, embedded newlines and doubled quote characters are supported. Headers must be unique and every row must have the same number of fields. Cell values stay text, including leading zeros. Spreadsheet formulas are not evaluated.
