Retain Leading Zeros in Excel for the Web

Using Text Format

To keep leading zeros in Excel for the web, apply the Text format to your cells. Click on the cell or select the range of cells where you wish to enter the numbers. Then, change the cell format to Text before typing or pasting the numbers. This will prevent Excel from dropping the zeros at the beginning of your numbers.

Handling Long Numbers

For numbers that are 12 digits or longer, you should use the Number format instead of Text. This action ensures that Excel does not default to Scientific format, which converts numbers after the 15th digit to zeros. Apply the Number format to maintain the integrity of long numbers.

Custom Number Formats

Microsoft Excel allows for custom number formats to display leading zeros. For fixed-length numbers, utilize a format like "00000" for five-digit numbers with leading zeros. For a nine-digit format with a hyphen, use "00000-0000". For variable-length numbers with leading zeros, apply a custom format such as "0"#.
