What is a .MMP file?
The most common data format on the web.
An MMP file is a MixMeister Studio or Fusion DJ project. It stores track references, BPM data, and mix cue points, but contains no audio. MixMeister Fusion is the only program that opens it, but the software reached end-of-life around 2012. If the file is XML inside, it may instead be an LMMS music project, which is a completely different format that shares the same extension.

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