Re: How to get to BUD/s at my age? Really? Wow thanks for the info, I had always been under the impression that you had to be 28 or younger to go to BUD/s unless you had a waiver. I didn't realize that if you had a contract before your 29th that you would still be eligible, because depending on attempts you could be well into your 30's.
XLSX is a file extension for an open XML spreadsheet file format used by Microsoft Excel. Microsoft introduced the open XML standard to Microsoft Office in 2007 after a push from business users who saw the value in an open file format for transferring data between applications and other areas of working with the files. Support can also be added to earlier versions of Excel with Open XML component support.
Conclusion. An Excel workbook saved as xlsx has many advantages over the old format xls. It is therefore recommended that you migrate all your xls files to the new format xlsx to benefit in Excel 2007, Excel 2010 and Excel 2013.
