Question 1

Frequently Asked Questions (FAQ) Is my TOML or JSON config uploaded to your servers?

Accepted Answer

No, absolutely not. All parsing and stringification operations run 100% inside your local browser tab using client-side JavaScript execution. Zero network packets or analytical payloads are transmitted to any backend.

Question 2

Why does converting a JSON array to TOML produce an error?

Accepted Answer

By definition in the official TOML 1.0 specification, the root of every TOML document must be a table (a key-value mapping). Therefore, top-level JSON arrays (like [1, 2, 3] ) cannot form a valid standalone TOML document. To convert them, wrap the array in an enclosing object such as &#123; "items": [...] &#125; , or use the one-click auto-fix button above.

Question 3

How does the tool handle null values in JSON when converting to TOML?

Accepted Answer

TOML does not have a null data type. In dictionary objects, null fields are omitted. In arrays, nulls are disallowed by TOML. When the "Filter Nulls" toggle is enabled, null values inside arrays are automatically pruned so conversion succeeds smoothly without errors.

Question 4

Can this tool parse complex Cargo.toml workspaces with multi-line dependencies?

Accepted Answer

Yes! Our parser is fully compliant with the TOML 1.0 specification, effortlessly handling Cargo workspaces, optional dependencies, conditional compilation feature flags, and custom release profiles.
