Privacy details

JSON TOML 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.

Options and local file

Optional settings apply only to this tab.

Your result

Reset reloads the tool with its starting values and releases open files and device controls. Saved drafts stay on this device until you delete them.

Links include your inputs and settings. Anyone with the link can see them, so leave out private text. Files and generated results are left out; random draws run again.

JSON TOML converter explained

Convert a JSON configuration object to TOML or a TOML document to JSON. Values that cannot cross the format boundary safely, including null, unquoted dates and unsafe large integers, are reported before output is offered.

Next: JSON to YAML converter

A worked example

{"enabled":true} becomes enabled = true in TOML. A null value is rejected because removing that property would silently change the configuration.

Before you use the result

Comments and presentation do not survive conversion. Dates and times must be quoted as text; the parser’s date normalization is not used. JSON decimal precision still applies. Some mixed table orderings may require simplification.
