Excel features

Data Security and Encryption

Why choose Excel?
XLSX belongs to the Office Open XML family documented in ECMA-376. According to Microsoft, XLSX cannot store VBA macros; XLSM is a different format. Keep the original workbook before changing file formats.

Excel Translation FAQ - Common Questions Answered
How do I translate an Excel file online?
Upload your XLS or XLSX file to ForgeFile, select your target language, and click Translate. Our AI translates only the text content while preserving all formulas, formatting, and charts.
Can I translate both XLS and XLSX files?
Yes. ForgeFile supports both modern .xlsx and legacy .xls formats. Both are translated with full preservation of formulas, formatting, charts, and data structures.
Are formulas preserved during translation?
Absolutely. ForgeFile identifies and protects all formulas, functions (VLOOKUP, SUMIF, etc.), and cell references. Only text content is translated - your calculations remain intact.
Does the translation preserve charts and pivot tables?
Yes. Charts, pivot tables, graphs, and sparklines are fully preserved. Chart labels, axis titles, and legend text are translated while the visual structure stays identical.
How many languages are supported for Excel translation?

Is there a file size limit?
The maximum file size depends on your plan. For larger files or bulk translation needs, contact us about enterprise plans with higher limits and API access.

What is the difference between ForgeFile and Google Translate for Excel files?
Google Translate cannot process Excel files directly and breaks formatting when copy-pasting. ForgeFile translates the entire spreadsheet file while preserving all formulas, charts, formatting, and multi-sheet structure.
