steam-ach-upload 0.1.0

Bulk-upload Steam achievements to the Steamworks partner portal via browser automation

steam-ach-upload

Bulk-upload Steam achievements to the Steamworks partner portal using browser automation (Playwright). Reads a CSV file of achievements and uploads each one — including icons — without you having to click through the portal manually.

Features

• Uploads name, description, achieved icon, and unachieved icon for every achievement in one run
• Browser opens visibly so you can monitor progress and intervene if needed
• Login session is persisted, so you only authenticate once
• --start N lets you resume mid-way after a failure
• --dry-run prints the upload plan without touching the browser

Requirements

• Python 3.10+
• uv (recommended) or pip

Installation

From source (recommended for development)

git clone https://github.com/rhedak/steam_achievement_bulk_upload
cd steam-ach-upload
uv sync
uv run playwright install chromium

From PyPI (once published)

pip install steam-ach-upload
playwright install chromium

CSV format

Create a CSV file with the following columns (see sample/achievements.csv for an example):

Column	Description
API Name	Steam internal achievement identifier (e.g. ACH_FIRST_STEPS)
Display Name (EN)	Name shown to players
Description (EN)	Description shown to players
Achieved Icon	Path to unlocked icon, relative to the CSV file
Unachieved Icon	Path to locked icon, relative to the CSV file

Icon paths are resolved relative to the CSV file's directory, so you can keep icons in a subfolder next to the CSV (e.g. icons/my_ach_done.png).

Usage

# Upload all achievements
steam-ach-upload 1234567 path/to/achievements.csv

# Preview what would be uploaded (no browser)
steam-ach-upload 1234567 path/to/achievements.csv --dry-run

# Resume from row 15 after a failure
steam-ach-upload 1234567 path/to/achievements.csv --start 15

# Use a custom directory for the browser session
steam-ach-upload 1234567 path/to/achievements.csv --profile-dir ~/.steam_browser_session

# Debug: open browser, click New Achievement once, print page HTML, then exit
steam-ach-upload 1234567 path/to/achievements.csv --debug

Replace 1234567 with your actual Steam App ID, found in the Steamworks dashboard URL: https://partner.steamgames.com/apps/achievements/YOUR_APP_ID

First run / login

On first run the browser will open to the achievements page. Log in with your Steamworks account, then the upload will start automatically. Subsequent runs reuse the saved session.

Running with uv (no install)

uv run --with steam-ach-upload steam-ach-upload 1234567 achievements.csv

Or from a local clone:

uv run python -m steam_ach_upload 1234567 achievements.csv

Running tests

uv run pytest

How it works

The portal requires achievements to be saved before icons can be attached. The tool therefore uploads each achievement in two passes:

1. Fill in the API name, display name, and description → Save
2. Re-open the saved row via Edit → upload achieved icon → upload unachieved icon → Save

If a row fails, the error is printed with the --start N command to retry from that point.
