Merge Excel Documents
Combine multiple Excel or CSV files into a single consolidated workbook safely and securely.
Combine Excel Files Online Safely
Merging spreadsheets from different sources is a common but tedious task. Our Excel Merger Tool simplifies this by allowing you to upload any number of workbooks and consolidate them into a single file with one click.
Professional Merging Logic
- Sheet Consolidation: Every sheet from every uploaded workbook is preserved and moved into the final file. No data is lost.
- Conflict Resolution: If multiple files have sheets with the same name, our engine intelligently appends suffixes (e.g., "Sales-2", "Sales-3") to prevent overwriting.
- Cross-Format Support: Mix and match XLSX and CSV files. We handle the conversion so your final export is always a clean, standard Excel workbook.
- 100% Client-Side: Your sensitive spreadsheets never touch our servers. All merging happens right in your browser, ensuring maximum privacy and security.
Ideal for:
Business Reports: Consolidate monthly sales or expense reports from different departments.
Data Cleanup: Gather disparate data sources into one central file for analysis.
HR & Payroll: Combine employee records or timesheets from multiple export files.
