ObjGen to JSON

Get more from ObjGen to JSON

ObjGen to JSON converts ObjGen definitions to JSON. ObjGen uses indentation, assignment lines, and optional type markers to describe nested data without writing every brace and quote. ObjGen resembles configuration syntax but is not standard TOML. Follow the tool example for array declarations and supported type markers. Use a numeric or boolean marker when the intended output must not be a string. Use the worked example to understand what a successful result looks like, then compare it with a small sample of your own input. Keep the original available until you have checked the output in its destination. Conversion establishes a representation; it does not establish that the underlying information is correct or that the receiving application accepts every supported feature.

How to use this tool

1. Enter or load ObjGen definitions using the input controls. Begin with the worked example or a small sample for which you know the expected result.
2. Review any available conversion options, then inspect the JSON result. Resolve a reported parse error at its source before attempting to reuse the output.
3. Check the example below against your own data. Use a numeric or boolean marker when the intended output must not be a string.
4. Copy or save the resulting JSON content using the controls provided, then validate it in the application or parser that will actually consume it.

SEE IT IN PRACTICE

A worked example

name = Ada
score n = 10

{"name":"Ada","score":10}

An unmarked value is a string; the n marker makes score numeric. Indentation creates more complex object structures.

Indentation and type markers

Start with the tool’s own sample when learning ObjGen. A line ending in an assignment creates a value, and indented lines describe child structure. Without a type marker, a numeric-looking value can remain a string. Validate the generated JSON after adding arrays or date markers so that the concise shorthand produces the schema you intended.

Build nested fixtures incrementally

Begin with a few assignments, then add one nested object and one array. Check the generated JSON after each addition so that indentation and type markers remain understandable. An unmarked numeric-looking value can become text, while a numeric marker expresses a number. Keep fixture values realistic enough to exercise your application: one simple object does not expose mixed-array behavior, optional properties, or empty collections.

When this tool is useful

• Prepare nested mock data while retaining a separate copy of the source.
• Use a small example to troubleshoot indentation and type-marker mistakes and identify a representation mismatch.
• Create JSON fixtures from concise definitions without manually rewriting every field or symbol.

Tips for a better result

• ObjGen resembles configuration syntax but is not standard TOML. Follow the tool example for array declarations and supported type markers.
• Use a numeric or boolean marker when the intended output must not be a string.
• After changing formats, compare meaningful values rather than whitespace alone. Read the JSON output with its intended parser when exact types or escaping matter.
