Usage:

./protonpass_to_keepassxc_csv.js protonpass_data.json protonpass.csv

OR

node protonpass_to_keepassxc_csv.js protonpass_data.json protonpass.csv

This will output a CSV of your ProtonPass export that you can use for KeePassXC imports and potentially others (unsure, have not tested other password managers).

You will need nodejs installed on your system.

Nik - I couldn't get this to work (see below). Any suggestions? Thanks!

%node protonpass_to_keepassxc.js data.json out.csv

        vault.items?.forEach(item => {
                    ^

SyntaxError: Unexpected token '.'

@swdrumm Are you using a newer node version? I'm using optional chaining there.

Other than that can't help much - I'm not using Proton Pass anymore.

@nikspyratos Installed node and npm from Ubuntu repo's today. node -v returns 12.22.9

@swdrumm That's definitely not the latest. Long story short Ubuntu usually pegs some or other stable-but-not-modern version of things. Look at nvm and installing latest node.

For ref, my node -v returns 18.16.0

@nikspyratos OK, thanks. I'll upgrade node.js to a version that supports optional chaining.

@nikspyratos Works great with the latest version of node.js
I didn't realize the Ubuntu repo version was that old. Thanks for the help!
