What is a .SESX file?
The most common data format on the web.
A SESX file is an Adobe Audition multitrack session file. It holds the layout, timing, and effects of your project as XML but contains no audio; the actual audio files must stay on disk beside it. Open it with Adobe Audition on Windows or macOS. No free alternative fully supports the format.

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