Transpose a table of data using Excel Formulas
Today lets tackle a familiar data clean-up problem using Excel – Transposing data.
That is, we want to take all rows in our data & make them columns. Something like this:
The easy solution – use Paste Special > Transpose
Long time Chandoo.org readers already know this. Excel has a built-in feature that lets you transpose data with a single click.
- Just select your original data
- Press CTRL+C to copy
- Go to an empty area and open Paste Special (CTRL+ALT+V)
- Select Transpose.
Although this approach works, it creates a copy of your original data. So whenever original numbers change, you must waste precious key strokes & time re-doing the transpose. This is exactly the opposite of awesome.
So, lets move to formulas.
Formula Solution #1 – Using INDEX & Helper cells to transpose a table
Lets say, we have named our original data as myData.
Lets also say myData has 6 rows & 7 columns. That means, the transposed table will have 7 rows & 6 columns.
- Create a 7×6 grid in your worksheet
- About this, write numbers 1 to 6 (cells D20:I20).
- Similarly, write numbers 1 to 7 beside it (cells B23:B29).
- Now use INDEX formula to transpose data like this:
- =INDEX(myData, D$20, $B23)
- Copy this formula all over and you are done!
See the illustration below to understand how this works.
Formula Solution #2 – Using INDEX formula & no helper cells
Sometimes, we cannot really use a helper column. That brings us to our next solution.
In above solution, the helper cells are giving us running numbers from 1 to 6 (and 1 to 7). We can use ROWS() and COLUMNS() formulas to generate these running numbers.
So our new formula will be
Once you write and copy paste this formula, it will automatically supply the required numbers to INDEX formula and does the magic.
How does it work?
Well, that is for you to figure out. See this illustration to get started.
Formula Solution #3 – Using TRANSPOSE formula
Do you know there is a formula that does all of this. It is called – TRANSPOSE !!!
What is TRANSPOSE formula?
TRANSPOSE formula takes a range of values (or an array) and transposes them and returns another array.
Since this formula always returns an array, we cannot use it in one cell. But we can select a range of cells & then write TRANSPOSE in them and press CTRL+SHIFT+Enter to get the values transposed.

How do you transpose your data?
I prefer using INDEX with ROWS & COLUMNS approach. This is very versatile & elegant. Also this approach lets me extract only a small window of large data set (by offsetting row & column numbers with something like scroll-bar position).
