## Extract numbers from a column

I this article I will show you how to get numerical values from a cell range manually and using an array formula. Lets get started, the steps below demonstrates how to select only numbers from cell range B3:B12 manually.

You don't need to select all cells containing numbers one by one, this trick willl save you a lot of time.

- Select cell range B3:B12 with your mouse.
- Press function key F5 on your keyboard.

- A dialog box appears, click "Special..." button.
- Another dialog box shows up, click "Constants".
Note, if your selection contains formula then click on "Formulas".
- Make sure checkbox "Numbers" is selected only, see image above.
- Click OK button.

- The selection changes to only selecting numbers, see image above.
- Copy these cells. (CTRL + c)
- Select a destination cell with your mouse.
- Paste selection. (Ctrl + v)

The image below demonstrates an array formula that extracts numbers only, this can be useful in a dashboard or interactive worksheets.

**Question**: I want to extract all numeric values into a new column?

If you have both letters and digits in a cell then read this article:

Array formula in C2:

To enter an array formula, type the formula in a cell then press and hold CTRL + SHIFT simultaneously, now press Enter once. Release all keys.

The formula bar now shows the formula with a beginning and ending curly bracket telling you that you entered the formula successfully. Don't enter the curly brackets yourself.

### Explaining formula in cell D3

#### Step 1 - Check if a value is a number

The ISNUMBER function returns TRUE if value is a number.

ISNUMBER($B$3:$B$12)

becomes

ISNUMBER({"VV"; "DD"; 5; 8; 5; "VV"; "RR"; "TT"; "DD"; 9})

and returns

{FALSE; FALSE; TRUE; TRUE; TRUE; FALSE; FALSE; FALSE; FALSE; TRUE}

#### Step 2 - Convert TRUE to corresponding row number

The IF function returns corresponding row number if the logical test is TRUE and nothing "" if the logical test is FALSE.

IF(ISNUMBER($B$3:$B$12), ROW($B$3:$B$12)-MIN(ROW($B$3:$B$12))+1, "")

becomes

IF({FALSE; FALSE; TRUE; TRUE; TRUE; FALSE; FALSE; FALSE; FALSE; TRUE}, ROW($B$3:$B$12)-MIN(ROW($B$3:$B$12))+1, "")

becomes

IF({FALSE; FALSE; TRUE; TRUE; TRUE; FALSE; FALSE; FALSE; FALSE; TRUE}, {1;2;3;4;5;6;7;8;9;10}, "")

and returns

{""; ""; 3; 4; 5; ""; ""; ""; ""; 10}

#### Step 3 - Return k-th smallest row number

The SMALL function makes sure that a new value is returned in each cell.

SMALL(IF(ISNUMBER($B$3:$B$12), ROW($B$3:$B$12)-MIN(ROW($B$3:$B$12))+1, ""), ROWS(D2:$D$2))

becomes

SMALL({""; ""; 3; 4; 5; ""; ""; ""; ""; 10}, ROWS(D2:$D$2))

The ROWS function returns the number of rows in a cell reference, in this case, the cell reference expands when the cell is copied to cells below.

SMALL({""; ""; 3; 4; 5; ""; ""; ""; ""; 10}, ROWS(D2:$D$2))

becomes

SMALL({""; ""; 3; 4; 5; ""; ""; ""; ""; 10}, 1)

and returns 3.

#### Step 4 - Return value

The INDEX function returns a value based on a row and column number.

INDEX($B$3:$B$12, SMALL(IF(ISNUMBER($B$3:$B$12), ROW($B$3:$B$12)-MIN(ROW($B$3:$B$12))+1, ""), ROWS(D2:$D$2)))

becomes

INDEX($B$3:$B$12, 3)

and returns 5 in cell D3.
