JSON Formatter
Validate JSON and create a consistently indented local review copy, with optional recursive key sorting.
Use the JSON Formatter
Validate JSON and create a consistently indented local review copy, with optional recursive key sorting.
Calculations, formatting and generation happen locally in your browser; this batch does not require an external processing service.
Local browser utility. Review transformed, generated or calculated output before production, publication, survey/set-out, SEO deployment or assessment use. GIS calculations state their coordinate assumptions explicitly.
How to use it
Start with the worked example, replace it with your real inputs, inspect the result and supporting details, then copy or export only after checking assumptions and source data.
How the JSON Formatter works
Validate JSON and create a consistently indented local review copy, with optional recursive key sorting. The methodology below explains the actual production transformation, the verified QA fixture and the support boundaries that prevent the page from overstating what it does.
Calculation breakdown
ToolLott will explain the current inputs and displayed result here.
Process the supplied data using the documented production transformation
The JSON Formatter follows a deterministic production workflow using Indentation, Sort object keys, JSON input. It validates the supplied inputs, performs this tool-specific operation — Validate JSON and create a consistently indented local review copy, with optional recursive key sorting — and reports the verified result “Valid JSON: 3 top-level key/value item(s)” without silently changing unsupported cases.
| Symbol / input | Meaning | Unit |
|---|---|---|
indent | Indentation | user input |
sortKeys | Sort object keys | user input |
input | JSON input | user input |
Step-by-step method
- Validate the required text, file, coordinates, options or output settings before processing.
- Validate JSON and create a consistently indented local review copy, with optional recursive key sorting.
- Return the production summary or downloadable artifact, while keeping unsupported formats, syntax or edge cases visible rather than silently guessing.
Worked example
Owen, a web developer, A release engineer has a compact JSON build record containing build number, pass status and three checks and wants syntax validation plus a consistent review copy before committing it.
Example inputs
- Indentation: 2
- Sort object keys: no
- JSON input: {"project":"ToolLott","release":{"build":18,"status":"passed"},"checks":["qa","mobile","regression"]}
Calculation / processing
Use the verified QA fixture: Indentation: 2; Sort object keys: no; JSON input: {"project":"ToolLott","release":{"build":18,"status":"passed"},"checks":["qa","mobile","regression"]}.Run the production JSON Formatter workflow using the documented production transformation for the supplied data.The production QA case reports: Valid JSON: 3 top-level key/value item(s).
This verified result shows what the JSON Formatter produces for the stated scenario. Interpret it together with the inputs, assumptions and limitations instead of treating the displayed summary as context-free advice.
Assumptions
- Input text/data follows the syntax, coordinate or formatting conventions stated on the page.
- Processing uses the browser/runtime features documented by ToolLott; no hidden correction is assumed unless the tool explicitly performs it.
Limitations
- Formatting, testing and transformation utilities cannot prove application-level correctness, security or interoperability beyond the documented operation.
- Browser, encoding, coordinate-datum, syntax and environment edge cases can require separate validation in the target system.
Common questions
What does the JSON Formatter actually calculate or change?
Validate JSON and create a consistently indented local review copy, with optional recursive key sorting. The methodology describes the production relationship or transformation rather than a generic description.
Does the worked example match the real ToolLott tool?
Yes. The example is linked to the production QA fixture for Build 0191, including its expected summary.
What should I check before relying on the output?
Review the stated assumptions, support boundaries and source references, and independently verify any result used for financial, engineering, legal, archival or production decisions.

A realistic way Owen could use this tool
Owen is a web developer.
A release engineer has a compact JSON build record containing build number, pass status and three checks and wants syntax validation plus a consistent review copy before committing it.
The page is prefilled around the scenario data: indent = 2; sort keys = “no”; input = “{"project":"ToolLott","release":{"build":18,"status":"passed"},"checks":["…”. On calculation/processing it returns Valid JSON: 3 top-level key/value item(s), which ties the example to a specific checkable outcome instead of an abstract promise.
The scenario resolves to Valid JSON: 3 top-level key/value item(s). That gives Owen the concrete quantity/text/file setting needed to validate JSON and create a consistently indented local review copy, with optional recursive key sorting, with the limits of the method still visible. The page also keeps this limitation explicit: Local browser utility.
Fictional scenario using realistic example data. For Ready tools, the worked result is tied to the tested example shown in the tool. Replace the figures with your own inputs and independently verify important professional, financial, legal, health or safety decisions.
