How Merging Works

Sheet Combination

• All sheets from File 1 are added first
• Then all sheets from File 2, File 3, etc.
• Sheet order follows file upload order
• Each sheet maintains its original structure

Sheet Naming Convention

• Format: FileName_SheetName
• Example: Sales2024_January, Sales2024_February
• If name exceeds 31 characters (Excel limit), it will be truncated
• Alternative format for long names: F1_S1_SheetName

Data Preservation

• All cell values preserved
• Formulas maintained as-is
• Cell formatting retained
• Sheet structure unchanged

File Size Limits

• Maximum 50MB per input file
• No limit on number of files
• Output file size depends on total data
• Large files may take longer to process

Tips for Best Results

1. Organize Before Upload: Upload files in the order you want sheets to appear
2. Check File Names: Ensure Excel files have descriptive names for clear sheet identification
3. Review Sheet List: Verify all sheets are listed before merging
4. Use Descriptive Output Name: Name the merged file clearly (e.g., "Q1_2024_AllReports")
5. Remove Unnecessary Files: Use the X button to remove files you don't want to merge
6. Check File Size: Keep individual files under 50MB for optimal performance
7. Avoid Duplicate Sheet Names: If source files have same sheet names, they'll be differentiated by filename prefix

Troubleshooting

File Not Loading?

• Check file format (.xlsx, .xls, .xlsm only)
• Verify file size is under 50MB
• Ensure file is not corrupted
• Try re-uploading the file

Merge Taking Too Long?

• Large files with many sheets take more time
• Multiple large files increase processing time
• Browser performance varies by device
• Wait for process to complete

Sheet Names Look Strange?

• Long filenames/sheet names are truncated to 31 characters
• This is an Excel limitation
• Rename source files to shorter names if needed

Some Sheets Missing?

• Check if all files loaded successfully
• Verify sheet count matches expectation
• Empty sheets are still included
• Re-upload missing files if needed
