Deepl API Integration Software Tool Python

Automatically translate your CSV and Excel files

A tool built to automate the translation of large product catalogs and accelerate the internationalisation of e-commerce sites, or simply to translate CSV and Excel databases.

This tool started from a recurring client problem: several Shopify stores had reached a critical product volume where internationalisation was no longer optional, but manually translating thousands of listings was impractical. The goal: reliably translate CSV and Excel exports without breaking the data.

The need

The request looked simple, translate product exports, but in practice it meant handling large volumes, specific business constraints and users with very different profiles, all while keeping the file structure intact.

The solution

The software ingests CSV and XLSX files, translates the right columns through DeepL and writes a clean output that preserves structure, ready to re-import into the store.

Key features

  • Batch translation of CSV and Excel files via DeepL
  • Structure-preserving output for safe re-import
  • Built for large product catalogs
  • Targets Shopify, WooCommerce and any tabular database

Results

Catalogs that took weeks to localise are translated in one pass, opening new markets without manual, error-prone work.
