How do I merge two Excel sheets into one?
Upload the workbook to DataSort. It detects every sheet inside, you tick the ones you want to combine, and the AI aligns their columns to the first sheet's schema, even when the headers don't match. Choose Append Rows to stack them or Sum Values to aggregate by ID, then export one merged table. No VLOOKUP, no Power Query, no macros.
- 1 Drop your workbook into the box above.
- 2 DataSort lists every detected sheet. Tick the ones you want to merge.
- 3 Pick a strategy: Append Rows to stack Jan + Feb, or Sum Values to aggregate numbers by ID or name.
- 4 Review AI Smart Mapping. It pairs each column across sheets with a confidence badge, and you can override any pairing.
- 5 Export the merged table as XLSX, JSON, or SQL.
What happens when you merge worksheets with AI
Every tab detected automatically
You don't list your sheets manually. DataSort reads the workbook, shows each worksheet it found in the staging view, and gives you Select All or Clear so you can combine twelve monthly tabs in two clicks.
Headers that don't match, matched anyway
AI Smart Mapping pairs Client Name with Customer with Name and shows a confidence badge for each pairing. This is the exact reason manual sheet merges fall apart, and it is handled before a single row moves.
Append rows or aggregate values
Choose Append Rows to stack January under February for a full-year view, or Sum Values to roll numeric columns up by ID or name so each entity ends up on one line with a correct total.
A VLOOKUP that cannot return #N/A
No lookup formulas, no exact-match arguments, no dragging a formula down 40,000 rows and praying. The mapping is semantic, so a trailing space or a different column order will not silently break your merge.
Duplicate records collapsed, not stacked
Entity resolution detects unique keys like Email or ID. If the same person appears in sheet one and sheet three, their data is combined into a single row instead of quietly becoming two rows in your final count.
Undo any merge instantly
If the combined result isn't what you expected, hit Undo and you are back to the previous state. You can try a different strategy without re-uploading the workbook and starting the whole job again.
Sheets across separate workbooks too
Multi-file upload works the same way. Drop several workbooks at once and the first sheet becomes the Master Schema that every other sheet is aligned to before combining.
Column order does not matter
Sheet A can have Email in column B and Sheet C can have it in column G. Mapping is by meaning, not position, so you never have to reorder columns by hand before merging.
Export the merged table anywhere
One combined table, three exports: XLSX for the client, JSON for a developer, or SQL insert statements for a database load. Same result, no re-doing the merge for each format.

How It Works: Technical Methodology
Smart Header Recognition
DataSort's AI understands that Client Name, Customer, and Name refer to the same thing across different worksheets. It unifies these headers into one Master Schema so the merge succeeds instead of producing a table with six half-empty columns.
Entity Resolution
Rather than blindly stacking rows, DataSort detects unique keys such as Email or ID. When the same record appears in two sheets, the values are combined into a single row, so your merged count reflects real entities and not duplicates.
