LastPass to Proton Pass converter

LastPass and Proton Pass both use CSV, but LastPass writes 8 columns; Proton Pass expects 11 in a different order — so Proton Pass rejects a raw LastPass export or silently files everything into the wrong fields. Drop your export below and get back a file Proton Pass accepts.

Convert your LastPass export

Drop your LastPass 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 LastPass 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 5 of 8 column names match (url, username, password), and they're in a different order — enough for Proton Pass to accept the file and then put your passwords in the wrong fields.

LastPass column	Proton Pass column	What happens
`name`	`name`	Same name, position adjusted
`username`	`username`	Same name, position adjusted
`password`	`password`	Same name, position adjusted
`url`	`url`	Same name, position adjusted
`totp`	`totp`	Same name, position adjusted
`extra`	`note`	Renamed and repositioned
`grouping`	`vault`	Renamed and repositioned
`fav`	`— none —`	Proton Pass has no favorite field. Written into notes instead of dropped.

What carries over

Field	LastPass	Proton Pass	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	Yes	No	Dropped — re-star your important entries after importing.
Custom fields	Yes	No	Flattened into notes as name: value pairs.
Multiple URLs per entry	No	No	Not in the source file
File attachments	Yes	No	No CSV export includes attachments. Download them out of LastPass separately before you close the account — this is the one thing people lose permanently.

Step 1 — Export from LastPass

Sign in to your LastPass vault in the browser extension or at lastpass.com.
Open Advanced Options → Export.
Re-enter your master password and complete the email confirmation if prompted.
LastPass either downloads a CSV or prints the data to a browser page — if it prints to the page, copy all of it into a plain text file and save it as .csv.

Watch out for

Secure notes come out in the same CSV as logins, with the note body in the "extra" column and url set to http://sn. Converters that ignore this turn every note into a broken login.
LastPass sometimes renders the export as an HTML page instead of downloading a file. Copy the raw text — do not save the page itself.

Step 2 — Convert it

Drop the file onto the converter above. It parses LastPass's layout, maps each field onto the universal record, then writes Proton Pass'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 Proton Pass 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 Proton Pass

Open Proton Pass → Settings → Import.
Choose the matching source, or "Generic CSV" if the source is not listed.
Upload the converted file and pick a destination vault.

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 4 — Verify and clean up

Open ten entries in Proton Pass at random and check them against LastPass.
Generate a 2FA code for one account in Proton Pass and confirm it matches LastPass. A TOTP secret that imported wrong fails silently until you're locked out.
Sign in to one real site using Proton Pass 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 LastPass account — and change any password you suspect was exposed while the plaintext file existed.

Questions

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

Only 5 of 8 column names match (url, username, password), and they're in a different order — enough for Proton Pass to accept the file and then put your passwords in the wrong fields. The converter rewrites the file into Proton Pass'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 LastPass to Proton Pass?

Proton Pass can't natively store: favorites, custom fields, file attachments. Rather than drop that data, the converter writes it into the notes field where Proton Pass has one, so you can move it back by hand. Keep your LastPass 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 LastPass exported the secrets. LastPass and Proton Pass 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 LastPass encrypted?

No. A LastPass 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 LastPass's export?

Secure notes come out in the same CSV as logins, with the note body in the "extra" column and url set to http://sn. Converters that ignore this turn every note into a broken login.

Anything unusual about importing into Proton Pass?

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.
