About:
fastgron is a command-line utility that converts JSON data into GRON (grep-able) format, creating discrete assignment statements for each JSON element. It significantly outperforms similar tools like gron, making it ideal for processing large JSON files. This format allows for easy filtering with standard grep and simplifies shell scripting operations on complex JSON data.
Key Features:
  • Extremely high performance compared to standard gron
  • Outputs grep-able assignment statements
  • Supports streaming and large file processing
  • Zero-dependency static binary
Use Cases:
  • Filtering large API responses or log files in JSON format
  • Debugging complex JSON structures in shell scripts
  • Extracting specific values from massive JSON datasets
Alternatives:
  • gron – Standard gron tool, significantly slower on large files
  • jq – More powerful query language but different output format
