What is a .PMP file?
The most common data format on the web.
A PMP file is an AutoCAD Plot Model Parameters file. It stores custom plotter calibration data and paper size definitions created by the Calibrate Plotter wizard. AutoCAD manages these files automatically; most users never need to open one directly. If you need to access the settings, go through AutoCAD's Plotter Manager in the Print/Plot dialog.

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