What is a .DSF file?
The most common data format on the web.
A DSF file is a DAZ Studio asset (DSON Support File). It holds 3D geometry, morphs, materials, and rigging for use in DAZ Studio (free). Open it by loading the asset through DAZ Studio's Content Library or by opening the .duf scene that references it. Note: .dsf is also used by an unrelated Sony DSD high-resolution audio format.

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