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.
File extensions are related to the file format, which is a computer programming term that specifies how information is coded for storage in a computer file. In the case of Excel, the current default file extension is XLSX and has been since Excel 2007. Prior to that, the default file extension was XLS. The difference between the two - besides the addition of the second X - is that XLSX is a XML-based open file format, while XLS is a proprietary Microsoft format.
