BulkPort Pro is an OpenCart 4.1 extension for large-file import and export workflows. Queue jobs for products, categories, manufacturers, customers, and orders; upload files in chunks; process them in the background; track progress live; resume interrupted imports; and download output files and error reports. Supports xlsx, csv, xls, and json. Built for stores that have outgrown fragile one-shot browser uploads and need a safer operational workflow for repeat bulk updates.
