jsonl-chronicle-extractor

What problem does it solve?

It eliminates the manual effort of searching through large JSONL log files to locate multi-line “Session Chronicle” narrative blocks buried inside nested text fields.

Core Features & Use Cases

• Targeted chronicle extraction: Parses JSONL line-by-line, inspects nested message.content[].text fields, and extracts entries whose text matches a regex.
• Regex-driven selection: Supports JavaScript-compatible regular expressions so you can precisely select a specific chronicle header (e.g., varying “Feb/February” spellings).
• Works for structured logs: Useful for extracting narrative blocks from progressive response logs or other JSONL exports that follow the expected message/content structure.

Quick Start

Run the script to extract all matching chronicles from a JSONL file by providing the file path and the regex pattern for the chronicle header.
