pytablewriter
pytablewriter is a Python library to write a table in various formats: AsciiDoc / CSV / Elasticsearch / HTML / JavaScript / JSON / LaTeX / LDJSON / LTSV / Markdown / MediaWiki / NumPy / Excel / Pandas / Python / reStructuredText / SQLite / TOML / TSV / YAML.
Decision gist · record as of 2026-08-14
Yes. pytablewriter is stable (Production/Stable status), actively maintained, has no known vulnerabilities, and solves a concrete problem—multi-format table serialization—with low install friction. Install it if you need to generate formatted tables in any of its supported output formats; skip it only if your use case is limited to a single format where a simpler, format-specific library would suffice.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Low friction installation with a pure-Python wheel.
- Active maintenance with recent commits; 7 runtime dependencies are all established libraries.
- No known vulnerabilities.

What it is and what it does
pytablewriter is a table serialization library that takes tabular data—from nested lists, CSV, pandas DataFrames, or other sources—and renders it into output formats spanning text markup (Markdown, HTML, LaTeX, reStructuredText), data interchange (JSON, YAML, TOML), spreadsheets (Excel, SQLite), and specialized formats (Elasticsearch, JavaScript, NumPy, Pandas source code). It handles automatic cell alignment, padding, number formatting, and optional styling like text color and font weight.
The library is designed for developers who need to generate formatted tables programmatically—whether for documentation, reports, data export, or display in notebooks. It abstracts away format-specific syntax so you write data once and output it in multiple formats by changing the writer class. Dependencies include setuptools, DataProperty, mbstrdecoder, pathvalidate, tabledata, tcolorpy, and typepy, all of which handle data validation, encoding, and styling concerns.
Use it for
- Generate Markdown tables for README files or documentation from Python data structures
- Export analysis results to Excel or CSV for sharing with non-technical stakeholders
- Create HTML tables for web pages or email reports from pandas DataFrames
- Build reStructuredText grid tables for Sphinx documentation from nested lists
- Serialize structured data to JSON or YAML formats for API responses or config files
- Write SQLite tables from in-memory data for persistence and querying
