WHAT IT HELPS WITH
Convert configuration without losing your place.
Choose readable output
Control indentation, wrapping, line numbers, and key sorting. JSON input can also be formatted without replacing the converted side.
Find the problem
When conversion cannot continue, the app points to the input location and explains the unsupported value or YAML structure.
SUPPORTED INPUT
Built for everyday configuration files.
JSON/YAML accepts source text through 10 MB. It supports common YAML collections, comments, anchors, aliases, and merge keys when they can be represented safely as JSON.
YAML input supports one document at a time. Custom tags and composite keys are not supported. Compatibility options can treat number, boolean, and null keys, as well as implicit timestamps, as text.

INCLUDED IN FREE
The complete conversion workflow.
Conversion, formatting controls, diagnostics, and copy are available in Free.
FORMAT YOUR WAY
Keep each editor comfortable.
JSON and YAML wrapping can be changed independently. Line numbers are shared, and optional key sorting lasts only for the current session.
LOCAL BY DEFAULT
Your configuration stays on your Mac.
Conversion and formatting run locally. Only display preferences are retained; your source and output are not stored by the workbench.
