What is a .CRC file?
The most common data format on the web.
A CRC file is a plain-text sidecar that lists filenames alongside their CRC-32 checksums, used to verify that downloaded or copied files arrived without corruption. Open it in Notepad to read the values, or use Total Commander or RapidCRC to actually verify the files. The .crc format is identical to the more common .sfv format.

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