SyncBatch – Bulk Contact Upload & Excel Contact Sync

Uploading Excel or CSV files enables instant contact synchronization to Android and iPhone devices. The process involves three simple steps: uploading a spreadsheet containing contact names, phone numbers, and emails; previewing the parsed contact list while automatically removing duplicates and mapping columns; and then syncing contacts instantly to Android Google Contacts or downloading as a vCard file for iPhone. The contact synchronization process is secure, with batch processing that syncs contacts in parallel without storing the contacts permanently. Duplicate contacts are automatically detected and skipped, ensuring a clean phonebook. The process works with both Android, through Google Contacts, and iPhone, via vCard files. The application is designed with privacy in mind, operating on a privacy-first architecture where uploaded contact files are processed in-memory for the duration of the sync and never stored in databases. Users can create teams, invite members, and send sync requests. Pricing is based on a pay-per-sync model with affordable credit packs available, and the first sync is free. Support is available via email with a response time of within 24 hours. The application adheres to the Google API Services User Data Policy and uses enterprise-grade encryption to keep data private. It is used by students, teachers, and institutions.
