Ndjson Python Packages

ndjson

ndjson with the same interface as the builtin json module

orjsonl

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

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

libscanio

Scan and filter structured data without loading it. Your family's RAM-friendly data scanner.

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.

claudestream

Drive Claude Code from Python: run it as a subprocess and read its output as typed events, with async and sync sessions, sandbox policies, and tools you define in Python

jsonl-diff

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

blazerules

A SIMD-accelerated, C++ rule engine, embeddable in pipelines. Evaluates declarative rules over event batches at memory-bandwidth speed

sqlitebiter

A CLI tool to convert CSV / Excel / HTML / JSON / Jupyter Notebook / LDJSON / LTSV / Markdown / SQLite / SSV / TSV / Google-Sheets to a SQLite database file.

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.

pyjsonlines

A Python library to convert Json to Jsonlines and Jsonlines to Json. This library is helpful to convert ndjson to Json and vice versa too.

bluerock-oss

Runtime visibility for Python MCP servers. Captures tool calls, session lifecycle, module imports (SHA-256), and subprocess execution as structured NDJSON. No code changes.

venn-bin

Row-level keyed diff of tabular datasets: parquet, CSV, NDJSON, Iceberg and Delta. One binary, no server and no SQL to write.
