Proton Pass to Bitwarden converter

Proton Pass and Bitwarden both use CSV, but Proton Pass writes 11 columns; Bitwarden expects 11 in a different order — so Bitwarden rejects a raw Proton Pass export or silently files everything into the wrong fields. Drop your export below and get back a file Bitwarden accepts.

Convert your Proton Pass export

Drop your Proton Pass CSV here or click to choose a file — nothing is uploaded

The conversion runs entirely in this tab using JavaScript. Your file is never sent to a server — you can confirm it by opening your browser's Network tab, or by turning off Wi-Fi before you drop the file in. Prefer not to do this in a browser tab at all? Download the converter and run it from your own disk.

Your export file is plaintext. Both the file Proton Pass gives you and the one you download here contain every password in readable form. Delete them as soon as the import is verified, and empty your trash.

What's actually different between the two formats

Only 2 of 11 column names match (type, name), and they're in a different order — enough for Bitwarden to accept the file and then put your passwords in the wrong fields.

Proton Pass column	Bitwarden column	What happens
`name`	`name`	Same name, position adjusted
`username`	`login_username`	Renamed and repositioned
`password`	`login_password`	Renamed and repositioned
`url`	`login_uri`	Renamed and repositioned
`totp`	`login_totp`	Renamed and repositioned
`note`	`notes`	Renamed and repositioned
`vault`	`folder`	Renamed and repositioned
`— none —`	`favorite`	Left empty — Proton Pass exports nothing for this.

What carries over

Field	Proton Pass	Bitwarden	Result
Item name / title	Yes	Yes	Carried over
Username and password	Yes	Yes	Carried over
Website URL	Yes	Yes	Carried over
Notes	Yes	Yes	Carried over
Folders / groups	Yes	Yes	Carried over
Two-factor (TOTP) secrets	Yes	Yes	Carried over
Favorites	No	Yes	Not in the source file
Custom fields	No	Yes	Not in the source file
Multiple URLs per entry	No	Yes	Not in the source file
File attachments	Yes	No	No CSV export includes attachments. Download them out of Proton Pass separately before you close the account — this is the one thing people lose permanently.

Step 1 — Export from Proton Pass

Open Proton Pass on the web or in the desktop app.
Go to Settings → Export.
Choose CSV, confirm with your Proton password.
Save the file.

Watch out for

Proton Pass splits identity between email and username. If your source only has one login field, the converter puts an address that looks like an email in the email column and everything else in username.
The vault column controls which Proton vault an item lands in. Folders from the source map onto it.

Step 2 — Convert it

Drop the file onto the converter above. It parses Proton Pass's layout, maps each field onto the universal record, then writes Bitwarden's exact expected columns — including the empty ones its importer requires and, where the two differ, the right shape for 2FA secrets. You'll see a preview and a list of anything Bitwarden can't hold before you download.

Rather not put this file in a browser tab connected to the internet? The same converter is available as a single HTML file you can download and open with your network switched off.

Step 3 — Import into Bitwarden

Sign in to the Bitwarden web vault at vault.bitwarden.com.
Go to Tools → Import data.
Under "File format", pick Bitwarden (csv).
Choose the converted file and select Import data.

Watch out for

Bitwarden prefixes bare domains with http:// on import. If you care about https, put the full URL in the login_uri column.
The free plan allows only two collections in an organization vault — import to your personal vault if your folder count is higher.

Step 4 — Verify and clean up

Open ten entries in Bitwarden at random and check them against Proton Pass.
Generate a 2FA code for one account in Bitwarden and confirm it matches Proton Pass. A TOTP secret that imported wrong fails silently until you're locked out.
Sign in to one real site using Bitwarden to confirm autofill works.
Delete both CSV files and empty your trash. If your Downloads folder syncs to iCloud, OneDrive or Dropbox, confirm the deletion propagated there too.
Only then close your Proton Pass account — and change any password you suspect was exposed while the plaintext file existed.

Questions

Why won't Bitwarden import my Proton Pass file directly?

Only 2 of 11 column names match (type, name), and they're in a different order — enough for Bitwarden to accept the file and then put your passwords in the wrong fields. The converter rewrites the file into Bitwarden's exact expected layout, including the column order and any empty columns its importer requires.

Do my passwords get uploaded anywhere?

No. The conversion is JavaScript running in your own browser tab — the file is read with the FileReader API, transformed in memory, and handed back to you as a download. There is no upload, no server-side processing and no analytics attached to the file. You can verify this by disconnecting from the internet before you drop the file in: the conversion still works.

What gets lost moving from Proton Pass to Bitwarden?

Bitwarden can't natively store: file attachments. Rather than drop that data, the converter writes it into the notes field where Bitwarden has one, so you can move it back by hand. Keep your Proton Pass account active until you've confirmed everything you need made it across.

Will my two-factor codes still work after the move?

Yes, as long as Proton Pass exported the secrets. Proton Pass and Bitwarden store them in different shapes — one uses a bare Base32 secret, the other a full otpauth:// URI — and the converter translates between them, which is the step most manual migrations get wrong. Check a couple of codes against your old vault before you delete it, since a TOTP secret that fails to import is silent until you're locked out.

Is the export file from Proton Pass encrypted?

No. A Proton Pass CSV export is plaintext — every password in it is readable by anything that can open the file, including other apps on your machine and anything that syncs your Downloads folder to the cloud. Convert it, import it, then delete both files and empty your trash. If your Downloads folder syncs to iCloud, OneDrive or Dropbox, check that the deletion propagated.

Anything unusual about Proton Pass's export?

Proton Pass splits identity between email and username. If your source only has one login field, the converter puts an address that looks like an email in the email column and everything else in username.

Anything unusual about importing into Bitwarden?

Bitwarden prefixes bare domains with http:// on import. If you care about https, put the full URL in the login_uri column.
