The Problem with Copy-Paste Translation

Anyone who has tried to translate an Excel sheet by copying text into Google Translate knows the pain. You lose:

Cell background colors
Text formatting (Bold, Italic)
Column widths and row heights
Formulas!

This necessitates hours of manual re-formatting.

The Solution: File-Level Translation

Modern tools like Excel Translator invoke APIs that read the underlying XML structure of the .xlsx file. This allows the translation engine to extract only the text strings, translate them, and place them back into the exact same XML node.

Key Benefits

Speed: Translate thousands of cells in minutes.
Accuracy: Context-aware AI understands "Table" as a furniture item or a data structure based on surrounding cells.
Integrity: Your VLOOKUPs and SUMs remain untouched.
