What is a .PDM file?
The most common data format on the web.
A PDM file is a Physical Data Model created by SAP PowerDesigner. It is a plain XML file describing database tables, columns, indexes, and foreign keys for a specific RDBMS (Oracle, SQL Server, MySQL, etc.). Open it in SAP PowerDesigner on Windows, or inspect the raw XML in any text editor. SAP PowerDesigner reaches full end of support in December 2027.

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