# WolfXL

> WolfXL is a fast Rust-backed Excel engine for Python. Keep familiar openpyxl-shaped code for a supported workflow, patch bounded changes into existing .xlsx and .xlsm workbooks, and keep Microsoft Excel out of the server path.

WolfXL ships in two editions. Community 2.0.9 is MIT-licensed on public PyPI with no credential. Commercial 2.1+ adds separately distributed production operations through the authenticated package index.

```bash
pip install wolfxl
```

Commercial 2.1+ requires the package credential issued on the checkout success page and uses the authenticated index as the sole index; this separate path does not gate or replace Community:

```bash
python -m pip install "wolfxl>=2.1" --index-url https://packages.wolfxl.com/simple/
```

- Engine implementation: A Rust-backed Excel engine with a public MIT Community edition and a separate Commercial distribution. The WolfXL documentation lists supported operations and known limitations.
- WolfSDK role: The Excel engine of WolfSDK.
- Downloadable qualification: Commercial packages install from the authenticated WolfXL package index with a per-purchase credential.
- Free rights: WolfXL Community is MIT-licensed on public PyPI and needs no credential.
- What payment adds: The Commercial 2.1+ distribution, direct support, and the production operations surface, under the WolfXL Order Terms.
- Platform boundary: Commercial wheels cover CPython on Linux, macOS, and Windows; the installation guide lists the exact Python range for each release.

The cited 2.1.0 clean-wheel release-artifact benchmark records 23 OpenPyXL comparison rows and 8 OpenPyXL memory rows. It is dated evidence for its recorded wheel and source, not a universal compatibility or release-quality claim.
