When you input a number in an excel cell and if the number needs to start with 0, you will find excel will remove all the zeros at the beginning of the number. In this article, I will tell you how to put 0 in excel in front of numbers with several methods.

### 1. Use Apostrophe To Put 0 In Excel In Front Of Numbers.

- Input the number
**001**in cell**A1**. - When you press the enter key, it will display the number
**1**in cell**A1**. - If you want to reserve the 2 zeros before the number 1, you should first input the apostrophe character (
**‘**) before**0**. - Now input the text
**‘001**in cell**A1**. - When you press the enter key now, it will display the number
**001**in cell**A1**also.

### 2. Format Cells To Put 0 Before Numbers In Excel.

- If you have multiple numbers in an excel column like below, and you want to put a fixed number of 0 in front of each number, you can use the format cell feature.

- Select all the above number cells, right-click them and click the
**Format Cells…**item in the popup menu list. - In the popup
**Format Cells**dialog, click the**Number**Â tab. - Click the
**Custom**item in the**Category**list. - Input the text
**000###**Â in the**Type**input box on the right side. - Click the
**OK**button to save the changes. - Now you can see the numbers have been changed as below.

- You will find that it does not add 0 in front of each number, this is because the total number of digits in the cell format text is 6 (
**000###**). - So if the original number contains less than 6 digits, it will add the related zeros in front of the original number.
- If the original number contains more than 6 digits, it will display the original number.
- So to put a fixed number of 0 in front of all the numbers, you should use the custom cell text format
**000######**in this example. - Then you will get the below cell data.
