What is a .CON file?
The most common data format on the web.
A .con file is a Corel WordPerfect Concordance File, a plain-text list of words and phrases that WordPerfect uses to generate an index with page numbers. Open it with WordPerfect Office or any text editor. If your .con file did not come with a WordPerfect document, it may be a configuration file from a different application.

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