Frequently Asked Questions
1. What types of Excel files can I merge using this tool?
You can merge any Excel files such as attendance sheets, salary sheets, registers, bank statements, MIS reports, or custom internal reports. The tool is designed to handle different formats, column orders, and structures, not just identical templates.
2. Do all Excel files need to have the same columns or format?
No. Files do not need to follow the same format. The tool intelligently detects headers, aligns similar columns, and merges data logically. However, extremely unstructured files may require manual review after merging.
3. How does the tool handle different or multi-row headers?
The tool automatically scans the file to identify the actual data headers, even if there are title rows. Headers that span multiple rows are merged. Non-data rows like titles or notes are ignored or handled separately during the merge.
4. Will the original data in my Excel files be changed?
No. Your uploaded files are never modified. The tool only creates a new merged Excel file, keeping all original data intact.
5. What happens if some columns exist in one file but not in others?
The tool creates a combined structure that includes all detected columns. If a column is missing in a particular file, the corresponding cells in the merged output will remain blank for those rows.
6. Is this tool suitable for large or professional datasets?
Yes. The tool is built for real-world business data, including multi-sheet files, varying formats, and large datasets. Still, users should always review the merged output before using it for reporting or compliance purposes.
