What is a .BPMN file?
The most common data format on the web.
A .bpmn file is a Business Process Model and Notation diagram - an XML file that describes a workflow (tasks, decisions, events and the flow between them) using the OMG BPMN 2.0 standard. Open it with the free Camunda Modeler or bpmn.io in a browser; draw.io also works. The file is plain XML and low risk to open, though in process-automation platforms it can contain executable scripts worth reviewing before deployment.

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