Read and navigate structured documents
Format supported code and data, switch between rendered and raw views, search within documents, fold sections, and jump directly to a line or structure node.
CodePrettify
CodePrettify is a JSON formatter and developer tools product for Chrome, Edge, and Windows. It helps users format, inspect, repair, compare, and generate code from structured data locally.
Overview
CodePrettify is a JSON formatter and developer tools product for Chrome, Edge, and Windows. It turns raw JSON responses, local files, and other supported code formats into a workspace for reading, validating, repairing, comparing, and exporting structured data.
The product is designed for local workflows. The homepage says it supports JSON, JavaScript, TypeScript, Markdown, XML, YAML, TOML, CSS, CSV, and RSS/Atom feeds, with the Windows app adding CSV and HTML support plus native local-file workflows. The pricing page says the currently shipped browser and Windows features are available to early testers for $0.
Features
Inspect and validate data
Use JSON Path, schema validation, diagnostics, statistics, and table or diagram views to inspect payloads without leaving the workspace.
Repair and transform JSON
Repair messy JSON-like input, review a repair report, and apply an ordered transformation recipe before exporting the result.
Generate code from JSON samples
Generate typed models or JSON Schema locally from a JSON sample, with support for TypeScript, Zod, C#, Java, Kotlin, Python/Pydantic, Go, Rust, Swift, Dart, and JSON Schema.
Compare documents semantically
Compare documents with a full-screen diff, including synchronized scrolling, swap sides, and a semantic mode that compares structure instead of formatting noise.
Developer utilities for testing and requests
Run regex tests, inspect HTTP responses, and use a sandboxed JavaScript playground for local testing and request workflows.
Use cases
Inspect raw JSON and structured responses
Format API responses or local files, expand nested objects, follow JSON Path queries, and validate a payload against a schema while staying in the same viewer.
Create code models from JSON samples
Paste a sample JSON object or array and generate typed models or a schema for downstream development work, then copy or export the result locally.
Clean up messy structured data
Repair malformed JSON-like content, review what was corrected, and reshape the data into a cleaner structure before sharing or exporting it.
Review changes without formatting noise
Compare two document versions and use semantic diff mode when key order or formatting has changed but the underlying data should be compared instead of the text layout.
Work through targeted debugging tasks
Search, test, and iterate on small snippets or requests with the regex playground, JavaScript playground, or HTTP client when you need quick local debugging.
Pros and Cons
Pros
- Supports multiple code and data formats beyond JSON, including Markdown, XML, YAML, TOML, CSS, CSV, and RSS/Atom feeds.
- Keeps core formatting, validation, conversion, comparison, and inspection workflows local to the device.
- Combines several workflows in one workspace, including JSON Path inspection, schema validation, diagramming, diffing, repair, and code generation.
- Offers both a browser extension and a Windows app, so users can choose a browser-centered or desktop workflow.
- The pricing page states there is no trial timer, subscription, payment details, or account required for early testers.
Cons
- The public pages only partially document some feature boundaries and product differences, especially between the browser extension and the Windows app.
- The available pages describe the product as early tester access, so future optional products or tiers may be priced separately.
FAQ
Is CodePrettify free to use right now?
Yes. The pricing page says early testers can install the browser extension or Windows app and use the currently shipped features for $0, with no trial timer, subscription, payment details, or account required.
Which platforms does it support?
CodePrettify is offered as a browser extension for Chrome and Edge, and as a Windows app in Microsoft Store. The pricing page also says you can install either product or both.
Does my data stay on my device?
The product is built for formatting, inspecting, repairing, transforming, comparing, and generating from local or browser-accessible code and data. The pricing page says core processing stays on your device, and the HTTP Client sends a request only when you press Send.
Is this a trial or a full product?
The source describes both products as early tester access rather than a restricted demo. The available features are the ones currently shipped, but the pricing page notes that future optional products or tiers may be priced separately.
Where can I learn how to use it?
The homepage and pricing page point readers to a one-page manual and feature guides. Those pages are the best starting point if you want setup, workflow, and feature details.
