What is a .WTF file?
The most common data format on the web.
A WTF file is a plain-text configuration file for World of Warcraft, stored in the game's WTF folder. Config.wtf holds your client and graphics settings as SET commands; Realmlist.wtf points the client at a server address (used mainly by private servers). Open or edit it in any text editor, but close WoW first and keep a backup, since the game rewrites Config.wtf on exit.

Frequently asked questions
Is my .WTF file uploaded anywhere?
No. The file is opened directly from the copy you pick.
My .WTF file is invalid. Can you fix it?
We show the exact line and column of the first error. For common problems like comments, trailing commas, single quotes or Python-style True/False/None, click Try to repair and download the fixed file.
How large can the file be?
Up to 50 MB. The tree only builds the branches you open, so even multi-megabyte files stay responsive.
What is JSONPath?
A path like $.orders[3].customer.email that points to one value inside the data. Click any node to see its path and copy it for code, jq or your API docs.
Can I see my data as a table?
Yes. Any array of objects can be shown in the Table view and downloaded as CSV.
