What is a .BML file?
The most common data format on the web.
A .bml file is most commonly a Bean Markup Language file - an XML configuration script created by IBM alphaWorks in 1998 to wire together JavaBeans components. Open it with any text editor (Notepad++, VS Code, or Notepad), since it is plain XML. The format is discontinued; the .bml extension is also used by two unrelated formats.

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