JSON Fixer information
What is JSON Fixer?
JSON Fixer is an online tool designed to save developers time by automatically fixing invalid JSON copied from logs, printed output, or other sources. Unlike traditional JSON formatters, JSON Fixer handles common issues specific to programming languages, such as Python’s None, True, and False, which often break JSON parsers. The tool instantly cleans, validates, and formats JSON so you can focus on development instead of manual debugging.
JSON Fixer is ideal for developers, QA engineers, data analysts, and anyone working with APIs or log data. Whether you need to repair a small snippet or a large JSON dump, JSON Fixer ensures your JSON is always valid and readable.
Why JSON Fixer?
- Automatically fixes invalid JSON from logs or printed code.
- Handles Python-specific values (None, True, False) without errors.
- Fast, online, and completely free.
- Copy-paste friendly — no setup required.
- Focused on real-world developer problems rather than just pretty formatting.
Alternatives / Similar Tools: While tools like JSONLint , JSON Formatter & Validator, and JSON Editor Online provide JSON validation and formatting, JSONFixer focuses specifically on messy JSON copied from logs or code, including Python and other language quirks, making it a time-saver for developers.
