🔥 Pain-Killer: Why Choose DeeplxFile?
| Traditional Tool Flaw | DeeplxFile Solution |
|---|---|
| DeepL Free doesn't support Excel | ✅ Perfectly handles Excel with formulas/comments |
| Google Translate caps at 10MB | ✅ No file size limit, 100-page docs in seconds |
| Formula logic breaks after translation | ✅ Cross-sheet references and nested formulas preserved |
| PDFs are not editable | ✅ Exclusive PDF-to-editable-Word conversion |
✨ Core Features: Beyond Translation
1️⃣ Complex Document Format-Lossless Translation
Excel Savior: Deeply compatible with multi-level formulas (VLOOKUP), conditional formatting, and comments. Function reference relationships are 100% preserved after translation—farewell to Google Translate's "#REF!" garbled output.
PDF → Editable Word (Windows Exclusive): Powered by the independent pdf2docxserver component:
- ✅ Maximum preservation of original PDF layout (charts/table of contents/headers/footers)
- ✅ API interface for Python application integration
- ✅ Outputs fully editable .docx files
💡 Tip: After downloading, double-click to run the server program and keep it open. DeeplxFile will automatically call the conversion service.
2️⃣ Dual-Engine Translation Modes
| Mode | Advantages | Best For |
|---|---|---|
| Direct Mode | Lightning-fast response, low resource usage | Small documents / daily lightweight translation |
| Playwright Mode | Simulates human operation, bypasses request limits, ✅ supports unlimited-length text | 100-page reports / sensitive data offline processing |
Tech Reveal: Playwright Mode uses Microsoft browser automation to control a browser, copies content to the DeepL web version for translation—achieving "human-level" compatibility.
3️⃣ Immersive LLM Translation
- Contextual Output: Specify translation requirements (e.g., "This is a business letter, use solemn tone"), let the LLM understand the scenario needs.
- Mixed-Language Handling: Force-lock the target language to avoid translation errors caused by mixed Chinese-English.
