Simple tool for de-duplicating bitwarden export files for accounts that don't use organizations or shared collections.

I needed it because some clients failed to sync and vault.bitwarden.com import does not deduplicate items or folders.

Usage

1. Create an export with duplicates
2. Create a de-duplicated file using cat export.json | node dedupe.js > deduped.json
3. Remove all items and folders using mass-select in vault.bitwarden.com
4. Sync all your clients
5. Import deduped.json in https://vault.bitwarden.com/#/tools/import
6. Sync all your clients
