Answer

To insert commas in Excel for multiple rows, modify cell formatting or apply a text transformation. Excel inserts commas to improve number readability or to structure text values.

Using Number Formatting to Add Commas

Number formatting adds commas to numeric values. Excel applies this formatting without changing the underlying value.

2. Press Ctrl + 1 to open Format Cells.

3. Select Number in the category list.

4. Set Use 1000 Separator (,).

5. Set the number of decimal places.

6. Click OK.

Mac

2. Press Command + 1 to open Format Cells.

3. Choose Number.

4. Set Use 1000 Separator (,).

5. Choose decimal places.

6. Confirm with OK.

Using Find and Replace to Insert Commas in Text

Text strings accept inserted commas as characters.

Steps

1. Select the rows containing the text.

2. Press Ctrl + H on Windows or Command + Shift + H on Mac.

3. Enter the target pattern in Find what.

4. Enter the comma placement in Replace with.

5. Click Replace All.

Using Flash Fill to Insert Commas

Flash Fill creates comma-formatted text when the transformation pattern is predictable.

Steps

1. Enter the version of the text with commas in the first row.

2. Move to the next row and type the transformed value.

3. Press Ctrl + E on Windows or Command + E on Mac to apply Flash Fill to the column.

Using CONCAT to Add Commas to Multiple Rows

The CONCAT function inserts commas between values in a combined text.

Steps

1. Create a helper column.

2. Enter a formula such as:

   =A1 & ","

3. Drag the fill handle down the column to apply the comma to all rows.

4. Copy and paste values if you need static text.

Using Power Query to Insert Commas for Structured Lists

Power Query creates comma-separated values when you need a list output.

Steps

1. Select the dataset.

2. Go to Data > From Table/Range.

3. Load the data into Power Query.

4. Select the column and choose Transform > Merge Columns.

5. Use a Comma as the delimiter.

6. Load back to Excel.

2. Text transformations create permanent comma characters in the cell.

3. Power Query helps when combining many rows into one comma-separated field.
