Need to expand your Excel spreadsheet? Adding columns is simpler than you think! Here's a quick guide to get you started.
**The Quick & Easy Method:**
1. **Right-Click:** Select the column header *to the right* of where you want to insert a new column. For example, to insert a column before column C, click on the 'C' header.
2. **Insert:** Right-click the selected header. A menu will appear. Choose "Insert".
3. **Voila!** A new column is instantly added to the left of your selection. All existing data shifts to the right.
**Adding Multiple Columns:**
1. **Highlight:** Select the *number* of column headers you want to insert. If you want three new columns, select three headers to the right of where you want the insertion.
2. **Right-Click & Insert:** Right-click on any of the selected headers and choose "Insert".
**Bonus Tip:** Use the keyboard shortcut 'Ctrl + Shift + +' (or 'Cmd + Shift + +' on Mac) after selecting a column header to quickly insert a new column. Practice these methods, and you'll be adding columns like a spreadsheet wizard in no time!
