FAQs
How do I merge cells in Excel without losing data?
Upload your Excel file, select the cell range, rows, or columns to merge, choose your separator (space, comma, or custom), and download the result. Unlike Excel's Merge & Center, our tool combines the content of every cell — no data is ever lost.
How do I merge two columns in Excel?
Upload your file, select the two columns you want to combine, choose your separator (space, comma, dash, or custom), and download the updated file with a new merged column. No CONCAT formula or Excel knowledge needed.
How do I merge first and last name in Excel?
Upload your file, select the First Name and Last Name columns, choose space as your separator, and download the result with a new Full Name column — 'John Smith' format for every row. Works for thousands of rows at once.
How do I merge two columns in Excel with a comma?
Select your two columns, choose comma-space as your separator, and our tool creates 'Smith, John' format for every row. Perfect for last name, first name format used in formal documents and directories.
How do I merge multiple columns in Excel?
Select all the columns you want to combine — 3, 4, or more — set your separators between each field, and our tool merges them all into one column in one pass. Perfect for combining address fields like Street, City, State, ZIP.
How is this different from Excel's Merge & Center?
Excel's Merge & Center is a visual formatting tool — it keeps only the top-left cell value and deletes everything else. Our tool combines the actual content of every cell with a separator. No data loss, ever.
How do I merge rows in Excel?
Upload your file, choose 'Merge Rows', select your key column (the column with matching values to group by), and our tool combines all rows with the same key value — concatenating data from other columns with your chosen separator.
How do I merge cells in Excel with a custom separator?
When setting up your merge, choose 'Custom separator' and type any character or text — dash, pipe, newline, or a word like ' and '. Our tool uses your custom separator between every merged cell value.
