Checking link lists is one of the useful feature of HTML Link Validator. You can supply a text file with the links you would like to test and HTML Link Validator will check all of them.

To validate link lists in txt files:

1.
Select "Validate HTML files on web server" and then select "I'll supply a list of files that should be validated"
(as on screenshot below).

2.
Type or paste or open from a file a list of links that you would like to validate.
A list should contain one url per line.
Click "Validate" to start validation.
