JSON Repair: Fix Malformed JSON Automatically

Fri, 01 May 2026 00:00:00 +0000

Few things are as frustrating as receiving malformed JSON from an API, a configuration file, or a data export. The error messages are often cryptic, and manually fixing the JSON in a large file is tedious and error-prone. JSON Repair (josdejong/jsonrepair on GitHub) solves this problem by providing a JavaScript library that automatically detects and fixes common JSON formatting errors.

Created by Jos de Jong – the same developer behind math.js – JSON Repair has become an essential utility in the JavaScript ecosystem. It handles a comprehensive range of JSON errors: missing quotes around keys, missing quotes around string values, trailing commas in objects and arrays, missing commas between items, single quotes instead of double quotes, unescaped newlines and tabs, truncated JSON, and even concatenated JSON strings.

Markdown has become the de facto standard for writing on the web, powering documentation, blog posts, comments, and technical communication across the internet. markdown-it (markdown-it/markdown-it on GitHub) is the JavaScript library that powers much of this ecosystem, providing a fast, extensible, and spec-compliant Markdown parser for Node.js and browser environments.

Developed by Vitaly Puzrin and Alex Kocharin, markdown-it has become one of the most widely used Markdown parsers in the JavaScript ecosystem, with over 20,000 GitHub stars and adoption by major platforms including VS Code, Ghost, and numerous static site generators. Its design philosophy balances strict CommonMark compliance with practical extensibility, making it suitable for both standard Markdown processing and specialized custom syntax.
