How to Add Columns
in Google Sheets

Open your spreadsheet and right-click on the column letter where you want to add a new column.

Choose “Insert column left” or “Insert column right” from the dropdown menu.

A new blank column will appear next to the selected column.

Enter data or formulas in the new column as needed.

If necessary, adjust the column width by dragging the column header separator.

Repeat the process to insert multiple columns or use “Ctrl + Z” to undo unwanted changes.
