Renkei ‑れんけい‑ is a powerful app designed to enhance data management capabilities for Shopify users, addressing the limitations of Shopify's standard export functions. With Renkei, users can extract columns not typically accessible through Shopify's built-in features, allowing for advanced data manipulation such as item extraction, reordering, and format modifications. The app ensures secure data handling by enabling downloads and integration with external servers through FTP, FTPS, and SFTP, without retaining output data internally, thus minimizing leakage risks. Users can automate these processes with schedule settings, facilitating efficient data management workflows. Developed in Japan, Renkei guarantees that all data storage occurs domestically, and it provides comprehensive support and documentation in Japanese, ensuring a seamless user experience. Whether converting data into UTF-8, Shift-JIS, or other formats, Renkei delivers versatile and reliable solutions tailored for the Japanese market.
