How to duplicate a column in excel

Answer

Duplicating a column in Excel creates an exact copy of the original column, including all values, formatting, and formulas.

Method 1: Using Copy and Paste

1. Select the column you want to duplicate by clicking the column header (e.g., A).

2. Press Ctrl + C (Windows) or Command + C (Mac) to copy the column.

3. Click the column header where you want to place the duplicate.

4. Press Ctrl + V (Windows) or Command + V (Mac) to paste the column.

This duplicates both the data and formatting.

Method 2: Using Drag with Ctrl Key

1. Select the entire column by clicking the column header.

2. Move your cursor to the edge of the selection until it changes to a four-sided arrow.

3. Press and hold the Ctrl key (Windows) or Option key (Mac).

4. Drag the column to the desired location.

5. Release the mouse button, then release the key.

This creates a duplicate column while keeping the original in place.

Method 3: Using Right-Click Menu

1. Click the column header to select the column.

2. Right-click and select Copy.

3. Right-click the destination column header.

4. Select Insert Copied Cells.

This inserts a duplicate column without overwriting existing data.

Notes

• Duplicating a column with formulas preserves the formula references exactly. Relative references adjust based on the new column location.

• Formatting, including colors, borders, and cell styles, duplicates along with the data.

• Large datasets may take a few seconds to duplicate, depending on your system.

This approach ensures you can replicate any column efficiently without losing data or formatting.
