Break Language Barriers Without Breaking Formulas or Budgets

Ever Struggled With These Scenarios?

  • Excel formulas turning into #REF! errors after translating financial reports?
  • Needing bilingual academic PDFs but finding no free tools?
  • Professional terms getting butchered in contract translations?

DeepLxFile Shatters All Limits with Open-Source Tech!

  • Cross-platform file translation with NO size restrictions
  • Powered by free DeepLx API · Terminal-friendly interface

🔥 Why DeepLxFile? The Ultimate Painkiller

Traditional Tools Fail DeepLxFile Solves
❌ DeepL Free blocks Excel ✅ Flawless Excel handling: Formulas / comments preserved
❌ Google Translate’s 10MB cap ✅ No file size limits: 100+ pages in seconds
❌ Formula logic breaks ✅ Intact cross-sheet references & nested functions
❌ PDFs remain uneditable ✅ PDF → Editable Word (Windows only)

✨ Core Features: Beyond Basic Translation

1️⃣Complex Format Preservation
  • Excel Savior: Handles VLOOKUP/conditional formatting/comments. Zero #REF! errors – unlike Google Translate.
  • PDF→Editable Word (Windows): Via standalone pdf2docxserver: ✅ Perfect layout retention (charts/TOC/headers) ✅ Python API for integration ✅ Outputs fully editable .docx

💡 Tip: Run this service in background – DeepLxFile auto-detects it.

2️⃣Dual-Engine Translation
Mode Advantage Best For
Direct API Blazing fast · Low resource Small docs
Playwright Bypasses limits · ✅ Unlimited text Sensitive data / 300+ page reports

Tech insight: Playwright mode automates DeepL’s web interface using Microsoft’s crawler framework for human-like compatibility.

3️⃣LLM-Powered Contextual Translation
  • Style commands: e.g., “Translate as formal business correspondence”
  • Mixed-language lock: Prevents mistranslations in bilingual docs.
