In Excel: select a column, right-click its letter and choose Insert — Excel adds the new column to the LEFT of the one you selected; the keyboard shortcut is Ctrl+Shift+Plus.

Click the column letter to the right of where you want the new column (Excel inserts to its left).
Right-click the selected column header and choose Insert.
The new blank column appears to the left and the existing columns shift right; formulas adjust automatically.
To add several at once, select that many column letters first; for speed, press Ctrl+Shift+Plus instead of right-clicking.
What this does
Inserting a column opens a blank column in the sheet and pushes the existing columns to the right to make room, with formulas re-pointing automatically. The direction is the thing to remember: Excel always inserts to the LEFT of the column you select, so to add a column between B and C you select column C and insert. Select several column letters first and Excel inserts that many new columns at once. Right-click the column letter ▸ Insert, or press Ctrl+Shift+Plus, and selecting the whole column (not just cells) keeps the insert clean down the full height of the sheet. The same idea underpins a lot of everyday Excel work, so the few minutes spent getting it right here pay back across every sheet you build afterwards. Treat it as a pattern, not a one-off, and it stops being something you look up and starts being something you reach for. The difference between a quick fix and a sheet you can trust is the extra minute you spend validating “add 2 columns in excel”. Start on a copy or a tiny sample, keep the affected columns visible, and compare the result with the tool above before you touch the real workbook. When this is a ribbon command, the selection matters more than the button: confirm the range, apply the command, then spot-check the output before saving. The point is a layout choice that keeps the sheet readable and sortable, but the practical win is that someone else can open the file and understand what happened without asking you.
A worked example
A table has Name in column B and Total in column C, and you want a new Region column between them. Because the insert goes to the left of the selection, click the column C header and right-click ▸ Insert: a blank column opens where C was, Total slides to column D, and the new empty column sits between Name and Total ready for "Region". To add two columns there instead, select columns C and D first, then Insert, and two blank columns appear to the left. Inserting a column makes room for a new field — a category, a calculated helper, a date — right where it belongs in the table, without retyping the columns beside it. Because the rest shift right and formulas re-point, the structure grows cleanly and stays correct. When the result is not what you expected, undo straight away rather than repairing it by hand — undo restores the sheet exactly, while manual fixes tend to leave small inconsistencies behind that surface later.
In Google Sheets
This is a command rather than a formula, so there is no syntax to carry over. Google Sheets arranges its commands in menus across the top instead of a ribbon, names some of them differently and does not have every Excel command — look for the equivalent in the Sheets menus or its help before assuming the steps match. Nothing on this page is behind a login or a download: the exact answer is at the top, and the detail below it is there for when you need it. That is the whole promise here — the answer first, and just enough context to make it stick. The short version of “add 2 columns in excel”: the answer is at the top of this page, and the sections above explain why each step matters, so a variation of the problem does not stump you. Try it once on a copy of a real file and the steps stick far better than re-reading them.
Common mistakes
- Expecting the column to the right — Excel inserts to the
LEFTof the selection, so select the column after the gap you want. - Selecting cells rather than the whole column letter, which opens the Insert dialog asking how to shift cells.
- Selecting one column when you need several — select as many columns as you want inserted.
- Assuming a
SUMor lookup range stretches to include the new column; a column added at the edge of=SUM(B:B)may be missed, so check the reference.
Frequently asked questions
How do I add a column in Excel?
Click the letter of the column to the right of where you want it, right-click and choose Insert (or press Ctrl+Shift+Plus). Excel inserts the blank column to the left of your selection and shifts the rest right.
Does the new column go left or right of my selection?
