I have no locked Excel Files and if I did it would be with a separate file lock program. Just my opinion.

A suggestion for Passfab is to include an option to keep a database of precomputed hashes as the user uses the program over time it generate its own database of precomputed hashes and keys to speed up subsiquent attacks on other files.

Al, no... just says submit success alert box and clears the form and presumably a spammy looking automated email will be sent and if it does not arrive we will be told to look in our spam folders or try a different email provider as they may block spamlike mail at connection and it never make it through to your account. Form is not compatible with IE9 patched up to August 2019 cumulative update.

TK,
My question was poorly worded. I wanted to ask if the application was installed and tried with Excel files. Did a protected .xlsx file get opened with this app by finding the forgotten password.

Al, ahhh right well I suspect I can answer that for you if it was an encrypted .xlsx file... and the encryption used was AES-128 or AES-256 then very probably that even using multi-CPU core, and all GPU cores and not having a stupid password like "password" or "12345678" or similar non-secure passwords then no, no one wil have cracked/recovered any passwords today by any form of brute forcing the files within the giveaway time slot. It is possible that if a password that is found in the used dictionary files in a dictionary attack then it should work ok. Or if the file was an XLS file using the old MS password protection then yes it should do as there plenty of free XLS file password recovery programs out there. But brute forcing AES-128 or AES-256 on a single desktop computer of modern spec is practically futile unless you are the lucky one in several trillion that the key is all 128 bits set to zero and that value is tried early in the attack or some similar statistically improbable coincidence.
