What is a .CDC file?
The most common data format on the web.
A CDC file is most likely one of two things: an internal driver-configuration plugin for Thermo Fisher's Chromeleon chromatography software, or a preview cache created by AutoCAD DesignCenter. Neither type opens in a general viewer. If it came from an AutoCAD folder, it is safe to delete. If it came from a Chromeleon lab installation, leave it alone or ask your Chromeleon administrator.

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