CONVERTER USER GUIDE

How it works

  1. Upload File: Drag and drop your `.xlsx` or `.xls` spreadsheet containing the external image links.
  2. Choose Parameters:
    • Select the target file format (PNG, JPEG, JPG).
    • Configure the Base URL (this should match where the app is hosted, e.g. `https://links-convert.noospherefactotum.com`).
    • Select the columns that contain the image links. The system automatically pre-selects columns containing typical image URLs.
  3. Run: Click the "CONVERT SHEET" button. The server downloads the images, converts them using `sharp`, saves them, and modifies the sheet cells in-place with new links.
  4. Download: Click the download button to grab the updated Excel file.

Coolify Persistence

The uploaded files are cleaned up immediately after conversion, and the converted images are saved in the data/outputs/ directory. Make sure you mount a persistent volume at /app/data in Coolify to ensure outputs persist across deployments.
