Importbench — Free CSV Import Workflow UI Kit
Importbench fills the gap between selecting a CSV file and trusting the records it creates. Every column is mapped explicitly, every record has a visible validation status, and a confirmation step explains which records will be skipped. The local contact register makes the result inspectable, while batch history supports one-step rollback of the latest import. This is a reusable interface and parser example for prototypes and front-end integration, with a 500-record limit and fictional seed contacts. Add authenticated server validation and durable transactions before connecting it to a production contact database.
