## jsoneditor.io

Most online JSON tools are single-purpose text boxes: one for formatting, another for validating, a third for converting YAML. jsoneditor.io folds that whole workflow into one tab. Because it is built on Monaco — the same editor engine that powers VS Code — you get syntax highlighting, code folding, multi-cursor editing, find and replace, and the keyboard shortcuts developers already have in muscle memory. Multiple files can stay open in tabs and folders, and the workspace is persisted in your browser so it is still there when you return.

Beyond editing, the tool offers several ways to look at the same data. The tree view lets you explore nested structures and right-click any node to copy its path as JSONPath, JavaScript, jq or JSON Pointer. The flow view renders data as a graph of connected nodes, which makes deeply nested API responses much easier to reason about. The query view runs JSONPath expressions live as you type, and the diff view snapshots the current file so you can compare it against another version, addition by addition.

Conversion is handled in place: JSON to YAML or CSV and back, plus TypeScript interface generation from a sample payload. The optional AI assistant can repair broken JSON, generate sample data, write a query or transform a file. Crucially, everything except that assistant runs locally in the browser, so pasted data never leaves your machine unless you explicitly ask the AI something. The service is free with no signup and is supported by advertising.

**Pricing & Plans:** jsoneditor.io is completely free with no account required. Formatting, validation, conversion, tree and query views and diffs have no usage limits; the site is funded by ads. The AI assistant is included at no cost but sends your open files to OpenAI when used.

- **Monaco editor with VS Code shortcuts:** Syntax highlighting, code folding, multi-cursor editing, find and replace, and the familiar VS Code keyboard shortcuts.
- **Tree, flow, query and diff views:** Inspect nested data as a collapsible tree, as a node graph, via live JSONPath queries, or compare two versions side by side.
- **Format, minify and validate:** Beautify or compact JSON in one click, with syntax errors underlined inline as you type.
- **Format conversion and type generation:** Convert JSON to and from YAML and CSV in place, and generate TypeScript interfaces from a sample payload in a new tab.
- **Optional AI assistant:** Ask the assistant to fix broken JSON, generate sample data, write a query or transform a file — files are only shared when you use it.

**Strengths:** Runs entirely in the browser, so sensitive data stays local except when the AI assistant is used; Free with no signup, ads or account required; Monaco editor delivers a genuine IDE-like editing experience; Tree, flow, query, diff and conversion features are unified in one workspace instead of scattered across sites

**Limitations:** The AI assistant sends your open files to OpenAI, so sensitive payloads should not be used with it; The interface is ad-supported, which some users find distracting

## PseudoEditor

Writing pseudocode usually means wrestling with a plain text editor: no highlighting, no error checking, no way to save your work across devices. PseudoEditor was created to fill that gap — the team describes it as the first browser-based dedicated pseudocode editor and compiler, and the core editor remains free to use.

The editor gives you dynamic syntax highlighting for keywords, functions, data types and conditionals, plus autocomplete for common constructs. A built-in compiler lets you test whether what you wrote actually behaves as intended, catching structural mistakes while you design the algorithm rather than after you have already translated it into code. Light and dark themes keep long sessions comfortable.

Paid features extend the editor into a learning and translation tool. PseudoEditor Pro unlocks an AI Tutor, intelligent code generation, and unlimited use of converters that translate pseudocode into Python, C++, and other languages, plus an ad-free interface. Schools and universities can also purchase institutional licensing with teacher controls and specification-aligned compilers.

**Pricing & Plans:** The editor and compiler are free to use and supported by ads. PseudoEditor Pro is a paid upgrade that adds the AI Tutor, code generators, unlimited converter use and ad removal; bulk institutional licensing is available for schools and universities.

- **Pseudocode editor with syntax highlighting:** Keywords, functions, data types and conditionals are highlighted, with autocomplete and light or dark themes to make writing algorithms faster.
- **Built-in pseudocode compiler:** Run your pseudocode in the browser to verify logic and surface structural errors before you translate it into a real language.
- **Cloud project saving:** Create a free account to store projects securely online and pick them up from any device, at home or in class.
- **AI code conversion (Pro):** Convert pseudocode into Python, C++ and other programming languages, with a large free allowance and unlimited use on Pro.
- **Exam board and institutional support:** Toggle syntax rules to match AQA, OCR, CIE, Edexcel and IB specifications, with bulk licensing and teacher controls for classrooms.

**Strengths:** Free core editor and compiler with no install required — it runs in the browser; Purpose-built for pseudocode, unlike general code editors that have no pseudocode mode; Covers major exam board specs (AQA, OCR, CIE, Edexcel, IB) which matters to students; Cloud saving and cross-device access for projects

**Limitations:** Advanced AI features such as the tutor and unlimited converters sit behind the paid Pro tier; The free version is ad-supported, which can distract during longer study sessions
