What is a .SRC file?
The most common data format on the web.
A SRC file is a plain-text source code file; the extension just means source. Open it in any text or code editor such as VS Code or Notepad++, read the first few lines to identify the programming language, then treat it as any source file of that type. Windows has no default app for .src because the extension belongs to no single program.

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