Description

Are you dealing with 10-digit numbers in Google Sheets and need to ensure they retain their leading zeros? Whether you're working with phone numbers, ZIP codes, or any other data requiring consistency in formatting, adding leading zeros is essential to maintain data integrity. Fortunately, Google Sheets offers simple solutions to accomplish this task efficiently.

Method 1. Custom Number Formatting

1. Select the Range: Highlight the cells containing your 10-digit numbers.
2. Format Cells: Right-click on the selected range and choose "Format cells" from the context menu.
3. Custom Number Formatting: In the "Format cells" dialog box, go to the "Number" tab. Under "Custom", enter the following format: 0000000000. This format tells Google Sheets to display the number with leading zeros to ensure it remains 10 digits long.
4. Apply Format: Click "Apply" to apply the custom number formatting to the selected range.

   
   

Method 2. Using the TEXT Function

1. Insert New Column: Insert a new column next to your 10-digit numbers if you want to keep the original data intact.
2. Enter Formula: In the first cell of the new column, enter the following formula: =TEXT(A1, "0000000000")
3. Copy Formula: Drag the fill handle (small square at the bottom-right corner of the cell) down to apply the formula to the entire column.
4. Values Only (Optional): If you want to convert the formulas to values, copy the cells with the formula, right-click, choose "Paste special", and then select "Values only".
   

Method 3. Using the ARRAYFORMULA Function with TEXT Formatting

1. ARRAYFORMULA: This function is a key feature in Google Sheets that allows you to apply a formula to an entire range of cells rather than just a single cell. It operates on arrays of data, making it particularly useful for handling large datasets and automating repetitive tasks.
2. IF Function: The IF function is a logical function that allows you to perform different actions based on specified conditions. It follows the syntax IF(condition, value_if_true, value_if_false). In the provided formula, the IF function is used to check if cell A1 is empty (A1=""). If it is empty, the formula returns an empty string (""). If not, it proceeds with the formatting operation.
3. TEXT Function: This function is used for converting a value to text with a specified format. It follows the syntax TEXT(value, format). In the formula, the TEXT function is applied to cell A1, formatting its contents with the specified format "000000000#". This format ensures that the number in cell A1 is displayed as a 10-digit number with leading zeros.

Formula

=ARRAYFORMULA(IF(A1="",,""&text(A1,"000000000#")))
