Stat Check Elo Scraper

This is a pure-Python scraper for the public Excel workbook embedded at:

https://www.stat-check.com/elo

It does not need Selenium, Playwright, Chromium, pandas, or openpyxl. It uses only the Python standard library.

How It Works

The Stat Check page embeds a public OneDrive Excel workbook through a 1drv.ms URL. Microsoft's web viewer does not expose a stable direct .xlsx URL in the page HTML, but it does use a public OneDrive metadata API behind the scenes.

The scraper reproduces the useful part of that flow:

1. Request an anonymous Microsoft "Badger" token from: https://api-badgerp.svc.ms/v1.0/token
2. Convert the public OneDrive embed URL into Microsoft Graph's shares/u!... id format.
3. Call: https://my.microsoftpersonalcontent.com/_api/v2.0/shares/{share_id}/driveItem?action=EmbedView with Authorization: Badger <token>.
4. Read @content.downloadUrl from the metadata response.
5. Download the real .xlsx.
6. Convert the first worksheet to CSV by reading the XLSX ZIP/XML structure directly.

The Microsoft endpoints used here are undocumented and could change, but this currently works without browser automation.

Usage

python3 pure_python_elo_scrape.py

Default outputs:

• elo-pure.xlsx
• elo-pure.csv

You can also pass output paths:

python3 pure_python_elo_scrape.py statcheck-elo.xlsx statcheck-elo.csv

Files

• pure_python_elo_scrape.py - gets the Badger token, resolves the workbook download URL, downloads the XLSX, writes CSV.
• download_and_parse.py - helper functions for downloading and converting XLSX to CSV with stdlib only.
• sample-elo.csv - sample output captured during testing.

Verification From Testing

On June 28, 2026, this downloaded a 3,465,320 byte workbook and produced a 4,145,399 byte CSV with 40,945 rows. The CSV header was:

Rank,Delta,Name,W,L,D,G,WR%,Elo,Delta,Last Event,Country
