## I. Keep leading zeros in Excel as you type.

I usually type ( **’** ) before font of number that has 0 as leading. Example, ‘01234. I think, it is simple do it.

If you don’t want type “ **‘** “, you can set se cell format is text.

+ Select the cell where you want to input 0

+ Right click and select **format cell**. The format cell dialog will appear, select **text** option at number group and click **OK**.

After you type a zero before number, excel will show a small triangle in the top left corner of the cell. To remove that error, click the warning sign and click ignore error.

## II. Custom number format.

+ Select the cell where you want to input 0

+ Right click and select format cell. Select custom option at number group and typing 0000 at type box and click OK. (For this example, I will create 4-digit number)

## III. Using formula of excel.

**1. Using CONCATENATE command.**

Formula: CONCATENATE(text1, [text2], …)

For this example, formula is CONCATENATE(0,B3) -> Input 1 0 number at the front of B3

**2. Using REPT and LEN command.**

Formula: REPT(0, number of zeros-LEN(cell))&cell

For example, I will create I will create 7-digit number: =REPT(0,7-LEN(B3))&B3

LEN(B3): Count all characters in cell B3

REPT(0,7-LEN(B3)) adds the required number of zeros. To know how many zeros will be added, the number is 7 subtract count all characters in cell B3.

**3. Use right command.**

Formula: RIGHT(“00000” & cell, string_length)

In this formula: “00000”: the maximum number zeros you want to get.

Cell: The cell you want to add zeros.

String_length: how many characters the resulting string should contain.
