What is a .INC file?
The most common data format on the web.
An INC file is a plain-text fragment, most often an HTML snippet (site header or footer) that a web server inserts into pages before sending them to the browser. Open it in any text editor: Notepad++, VS Code, or Vim. The browser never receives the .inc file directly; it is processed entirely server-side.

Frequently asked questions
Is my .INC file uploaded anywhere?
No. The file is opened directly from the copy you pick.
My .INC 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.
