Each of the three merge modes produces different results. Choosing the right one better meets your actual needs. The table below compares them in detail:

Merge mode Result Best for
Files → Sheets Each file becomes an independent worksheet, with the file name as the sheet name Scenarios that need clear data sources with separate file management
Files → Single sheet All files' data is appended to the same worksheet Consolidating multiple identically structured datasets into one master table
Sheets → Single sheet All worksheet data is merged into one table regardless of file boundaries Consolidating data across multiple workbooks/worksheets

FAQ

What is the Excel merge tool?

The Excel merge tool is an online spreadsheet merging utility. It merges multiple Excel files or worksheets into a single file, supporting multiple merge modes, header handling options, and output formats — all processed locally in your browser with no file upload required.

How do I use the Excel merge tool?

It's very simple. Upload multiple Excel files, choose the merge mode and header handling, then click "Start". You can also drag files to reorder them for a custom merge sequence.

Which Excel formats are supported?

Common formats such as .xlsx, .xls and .csv are supported. Output can be either .xlsx or .csv.

Will the original files be changed after merging?

No. The tool generates a brand new Excel file; the original uploaded files remain untouched — feel free to experiment.

Can worksheets with different column counts be merged?

Yes. The tool automatically aligns columns to the maximum column count across all worksheets, filling missing columns with blanks.

In what order is the merged data arranged?

By default, data is arranged in upload order (normal); selecting "Reverse" flips the order. For finer control, drag files to reorder them after uploading.

Is processing secure? Will my files leak?

Completely secure. Files are processed entirely in your local browser and never uploaded to any server — your data is absolutely safe.

Do I need to register or pay?

Free uses are granted every day, so everyday usage costs nothing. We provide a daily free credit that easily covers light needs; when you require higher processing volume, upgrading to member unlocks more benefits.

How many files can be merged?

Multiple files can be batch-uploaded. Performance depends on device memory — for large or numerous files, we recommend keeping individual files under 50MB.

Will the formatting get messed up after merging?

No. The tool preserves the original styling as much as possible, including fonts, colors, and borders. The merged output is based on the first file's settings.

How is the online version different from desktop spreadsheet software?

The online version is far more convenient. No installation needed — it's open-and-use with equally professional results, perfect for consolidating spreadsheets anytime, anywhere.

Are the merge results accurate?

Results are accurate and reliable. The tool strictly merges according to upload order and the mode you select, fully preserving rows and columns across multiple files and worksheets.
