What is a .AVASTLIC file?
The most common data format on the web.
An AVASTLIC file is a license activation file that Avast emails to customers after a paid subscription purchase. On a PC with Avast installed, double-clicking the file imports the license and registers the product. The main concern is scams - "free avastlic" and "license generator" downloads are a known malware vector; only use a file from Avast directly.

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

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.
