How to Upload Your Collection

Uploading your collection is currently only supported if you have Firestone.

How to Find your collection.json file:

1. Open File Explorer: Click the folder icon on your taskbar or press Windows key + E.
2. Go to Your Main Drive: Click on your main drive (usually labeled C:).
3. Find the Users Folder: Open the Users folder.
4. Open Your User Folder: Double-click the folder with your username (e.g., "John" or a number).
5. Access AppData: Enable Hidden items (under the View tab > Show/hide) to see and open the AppData folder.
6. Go to Roaming: Open the Roaming folder inside AppData.
7. Find the Overwolf Folder: Look for and open the Overwolf folder.
8. Locate the Random String Folder: Inside the "Overwolf" folder, there should be a folder with a random letter combination like "lnknbakkpommmjjdnelmfbjjdboc".
9. Find the JSON File: Inside this random string folder, look for a file named collection.json—this is the file you're looking for.
10. Open or Use the File: You can now upload the collection.json to this site!

Tips:

• If you can't see AppData, turn on "Hidden items."
• Search for "collection.json" if the path is unclear.
• Folder names may vary based on your language or username.
• Make sure Firestone and Hearthstone were running at the same time to generate / update your collection file.
