Frequently Asked Questions
Can this convert Kubernetes manifests and Helm charts?
Yes. It handles complex Kubernetes manifests including multiline config maps, env secrets, and pod specs with full fidelity.
How does TOML conversion handle deeply nested structures?
When converting JSON or YAML to TOML, nested objects are structured into standard TOML
[sections] and arrays of objects are rendered as [[array_of_tables]] according to TOML v1.0.0 specs.Is there any file size limit?
Because conversion is executed client-side, the tool can comfortably convert configurations up to several megabytes in under 50 milliseconds.
