 # Testing / Validating your Spreadsheets
 
 A wise word of advice, when testing your spreadsheets I recommend to use Excel instead of LibreOffice. This is because I have seen through testing, that where LibreOffice seems to just let most incorrect things just slide on through, Excel will not even open the spreadsheet as apparently it is much more strict about the spreadsheet validations. This will help you better identify any incorrect styling or customization issues.
