🔥 Why DeepLxFile? The Ultimate Painkiller

Traditional Tools Fail DeepLxFile Solves
❌ DeepL Free blocks Excel ✅ Flawless Excel handling: Formulas / comments preserved

✨ Core Features: Beyond Basic Translation

1️⃣Complex Format Preservation

  • PDF→Editable Word (Windows): Via standalone pdf2docxserver: ✅ Perfect layout retention (charts/TOC/headers) ✅ Python API for integration ✅ Outputs fully editable .docx
