Tool guide
Free Online Excel Workbook Merger
Combine the worksheets from two or more XLS or XLSX files into one new XLSX workbook in your browser. Each source sheet stays separate, is named from its source file and worksheet, and receives a unique name when collisions occur.
Steps
How it works
- Choose at least two supported Excel workbooks.
- Review the selected files in their selection order.
- Copy every source worksheet into one new workbook.
- Download merged-workbook.xlsx after processing finishes.
Highlights
Key features
- Accepts multiple XLS and XLSX workbooks in one selection.
- Copies each source worksheet into the combined workbook rather than appending all rows to one master sheet.
- Keeps file and worksheet iteration order from the selected input list.
- Builds Excel-safe sheet names from the source filename and original worksheet name.
- Adds numeric suffixes when generated sheet names would collide.
Use cases
Common uses
- Collect worksheets from several reports in one XLSX file.
- Package related workbooks while keeping their sheets separate.
- Combine monthly or departmental workbook tabs for easier distribution.
- Create one download from multiple authorized spreadsheet files.
Notes
Limitations to know
- This tool combines worksheets; it does not merge matching rows or consolidate data into one master sheet.
- The interface requires at least two files and has no explicit file-count limit, reorder control, or per-file removal control.
- Cross-workbook formulas, external references, named ranges, hidden-sheet settings, macros, charts, images, comments, and advanced workbook objects may not survive correctly.
- Styles and other workbook features are preserved only where supported by the parser and writer; complete fidelity is not guaranteed.
- Large workbooks can require substantial browser memory, while password-protected or corrupted files may fail.
FAQ
Frequently asked questions
Are worksheets kept separate?
Yes. Every source worksheet is appended as its own sheet in the new workbook.
Can I reorder the files?
There is no separate reorder control. Worksheets are added according to the selected file order and each workbook's sheet order.
What happens to duplicate sheet names?
Names are built from the source filename and worksheet name, sanitized for Excel, and given numeric suffixes when needed.
Are formulas and formatting preserved?
Supported worksheet cells may carry through, but cross-workbook formulas and advanced styles or workbook objects are not guaranteed to remain intact.
Can XLS and XLSX files be mixed?
Yes, both extensions are accepted where the spreadsheet parser can read them, and the combined download is written as XLSX.
