Here are some tips to help you get the best results with number formatting:

1. Apply number formatting to an entire column: If you want to use a column for a certain type of data, like dates or percentages, it’s easiest to select the whole column. Click the column letter, then apply the number format you want. This way, any data you add later will automatically have the right format. Just keep in mind that the header row usually won’t be affected.

   
   
   

2. Double-check your values after applying number formatting: If you apply number formatting to existing data, you might get unexpected results. For example, if you apply percentage formatting to a cell with the value 5, it will show 500%, not 5%. In this case, you would need to retype the values correctly.

   
   
   

3. Number formatting in formulas: If you use a cell with number formatting in a formula, the spreadsheet might apply the same format to the new cell. For example, if a cell with currency formatting is used in a formula, the result will also show as currency.

   
   
   

4. Use the text number format for exact values: If you want your numbers to appear exactly as entered, use the text format. This is useful for things like phone numbers, zip codes, or numbers that start with 0, like 02415. For best results, apply the text format before entering the data into the cell.
