Jsonl Python Packages

cc-transcript

Grep every Claude Code session you've ever run.

orjsonl

A lightweight, high-performance Python library for parsing jsonl files.

unlimitedpipe

Pipe the public internet: Unix commands that turn feeds, APIs and web pages into events, detect what changed, and publish free hosted feeds. Yahoo Pipes, rebuilt for the terminal.

dtflow

Inspect, clean, transform and ship LLM training data from one CLI; dt view is the interactive entry point.

convmerge

Merge heterogeneous chat/text sources into a single LLM training format (JSONL)

py-jsonl

Zero-dependency Python library for JSON Lines — read, write, compress, and stream in one line of code.

undatum

undatum: a command-line tool for data processing. Brings CSV simplicity to NDJSON, BSON, XML and other data files

csvpath

Data Engineering infrastructure that controls inbound tabular data file feeds and validates data contracts

iterabledata

Iterable Data is a Python library for reading and writing data files row by row in a consistent, iterator-based interface. It provides a unified API for working with various data formats (CSV, JSON, Parquet, XML, etc.) similar to csv.DictReader but supporting many more formats.

tg-chat-dump

Dump a whole Telegram chat or forum, one folder per topic, at 100k+ messages a minute: parallel workers, multiple accounts, Telegram's export mode, resumable SQLite.

strictspec

Define a schema once in TOML, and generate the full toolchain in your language: validation, versioning, migrations, etc. -- First-class support for Go, Python, and TypeScript

better-bing-image-downloader

Python library + CLI to bulk-download images from Bing or DuckDuckGo. Embeddable API, async, typed errors, JSONL manifest for ML training data. Good first issues available.

toolong

A terminal application to view, tail, merge, and search log files (plus JSONL).

cozempic

Context cleaning for Claude Code — prune bloated sessions, protect Agent Teams from context loss, auto-guard with tiered pruning

reqstorm

Send thousands of HTTP requests from Python or the command line: per-host rate limits, retries with backoff, pagination, progress and logs, results straight to JSONL, CSV, SQLite, PostgreSQL or MySQL.

jsonl-diff

A lightweight, pure-Python tool for comparing large JSONL/NDJSON datasets without loading them entirely into memory.

exform

Reshape text by example: show it a couple of before⇒after lines, it infers the transform and applies it to the whole file/stream — or emits a portable awk/python one-liner. Deterministic, offline, no regex, no LLM.

fmjl

FMJL: a document format that packs Markdown, LaTeX and HTML inside JSON Lines, one element per line. Spec, reference tool and VS Code.

plasmite

Easy interprocess communication based on persistent JSON message queues

claude-session-backup

Git-backed Claude Code session backup with timeline view, folder analysis, deletion detection, and session restore

jsonl-viewer

A terminal viewer for JSONL/NDJSON files. Browse records, search nested JSON, and inspect long strings in logs, datasets, and LLM agent traces.

mmap-chunker-core

Record-aligned byte-range planning for large immutable files, with zero-copy mmap framing, CLI, and a stable C ABI.

agents-traces

Ultra-fast, zero-bloat local JSONL observability and tracing for AI coding agents (MCP + CLI).

observra

Observra is an open-source observability and telemetry framework designed for AI and agentic systems, providing deep visibility into agent behavior, execution flows, runtime events, and inter-agent communication.
