Python 3 script to convert Dashlane csv-export to Bitwarden importable csv

README.md

Dashlane web export to bitwarden vault

I have only tested it on linux but it should work on windows+macos too.

To use:

1. Make sure python 3 is installed
2. Export the data from dashlane by visiting the web app, then pressing "My account" > "Settings" > "Export Data"
3. Unzip the .zip-file downloaded from dashlane
4. Download this script and put it in the same folder as the unzipped dashlane files
5. Open a terminal in the folder where the csv-file is located
6. Run python convert.py credentials.csv -o bitwarden.csv
7. Open the bitwarden web app
8. Go to "Tools" > "Import data"
9. Select the format "Bitwarden (csv)"
10. Select the file bitwarden.csv in the folder of your unzipped dashlane export
11. Press "Import data"

Note: This script only converts your passwords saved in dashlane, not secure notes, saved payment options or personal information.

from csv import DictReader, DictWriter
import argparse
import io

parser = argparse.ArgumentParser(description="Convert Dashlane csv-export to Bitwarden importable csv")

parser.add_argument("file", type=str, help="Dashlane credentials.csv-file to convert")
parser.add_argument("--output", "-o", type=str, help="Output csv file")
args = parser.parse_args()

new_fields = [
    "folder",
    "favorite",
    "type",
    "name",
    "notes",
    "fields",
    "reprompt",
    "login_uri",
    "login_username",
    "login_password",
    "login_totp"
]

with io.open(args.file, encoding="utf-8-sig", newline="\n") as file:
    data = DictReader(file)

    with io.open(args.output, "w", newline="\n") as file_new:
        writer = DictWriter(file_new, fieldnames=new_fields)
        writer.writeheader()

        mapping = {
            "username": "login_username",
            "title": "name",
            "note": "notes",
            "category": "folder",
            "url": "login_uri",
            "password": "login_password",
            "otpSecret": "login_totp",
        }

        for row in data:
            new_row = {}
            for key, value in row.items():
                if key in mapping:
                    new_row[mapping[key]] = value

            if row["username2"] or row["username3"]:
                new_row["fields"] = f"username2: {row['username2']}"
                if row["username3"]:
                    new_row["fields"] += f"\nusername3: {row['username3']}"

            writer.writerow(new_row)

I get (on MacOS) using Python 3.8.5

Traceback (most recent call last): File "convert.py", line 50, in if row["username2"] or row["username3"]: KeyError: 'username2'

Is this is only designed to work on the credentials file and not securenotes etc? No matter though because bitwarden imports dashlane csv files anyway ...

Yes, it only works on credentials. Bitwarden only imports the dashlane csv from the PC client (which has been deprecated and doesn’t work natively on linux etc) and not the web app. This script allows you to convert the .csv file that is downloadable from the web app :)
