What is JSON / INI Converter?
JSON and INI Converter targets simple settings used by servers, desktop applications, and developer tools. Root scalars become ordinary keys and one-level objects become sections; imported values remain strings so ports, versions, leading-zero identifiers, and switch text are not guessed incorrectly. Common workflows include the following. Create a simple INI file from JSON settings. Turn application INI into structured JSON for review. Detect duplicate sections, duplicate keys, and quoting errors. The page also documents input boundaries, output behavior, and practical cautions so you can review the result before putting it into an application, configuration, test, or production workflow.
When to use it
- Create a simple INI file from JSON settings.
- Turn application INI into structured JSON for review.
- Detect duplicate sections, duplicate keys, and quoting errors.
How to use it
- Choose the JSON or INI direction.
- Confirm the structure uses root scalars and one-level sections.
- Convert and resolve duplicate-key errors.
- Review string values against the destination application.
- Load one of the realistic examples first to verify the selected options and processing direction before replacing it with your own data.
- Review the output, status message, and documented limits; copy, download, or continue only after the result matches your expectation.
Runnable examples
The “Example 1” and “Example 2” buttons load the matching inputs. They cover different structures, directions, or boundaries and can be run directly in the workspace.
Example 1
{"app":"JSONLane","locale":"en","server":{"host":"localhost","port":8080}}Example 2
app=JSONLane
locale=en
[server]
host=localhost
port=8080Input rules
- JSON may contain root scalars and one level of scalar sections.
- Each effective INI line must be a section or key=value entry.
- Duplicate names and dangerous object keys are rejected.
- Text input is counted before processing and is limited to 1,000,000 characters on this page; file modes apply the separate file limit shown in the workspace.
- Only root scalars and one section level are supported.
Output rules
- Root JSON scalars become keys outside a section.
- Imported INI values remain strings.
- Comments and source layout are not represented in JSON.
- Output reflects only the current input, direction, and options; rerun after changing a mode or value instead of treating an earlier result as current.
- INI values remain strings when imported.
Limitations and cautions
- Only root scalars and one section level are supported.
- INI values remain strings when imported.
- Application-specific INI dialects may use different escaping.
How your data is handled
All parsing, conversion, binary encoding, and intermediate data remain in the current browser tab. JSONLane does not upload the input or retain it after refresh or close.
