Python Streaming JSON Formatter That Works with Existing Serializers
A new Python tool called jsonfold offers a solution for formatting JSON data in a way that is both compact and human-readable. It acts as a filter between existing JSON serializers and the output stream, allowing for configurable formatting behavior. This tool aims to provide a middle ground between machine-optimized output and overly verbose pretty-printed JSON.
- ▪Jsonfold allows users to control the level of compactness in pretty-printed JSON output.
- ▪The tool operates directly on the pretty-printed token stream generated by existing serializers.
- ▪Jsonfold maintains the functionality of existing serializers while improving the readability of the output.
