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.
That is because Microsoft has opened the Excel file format and decided to break the insides into XML files. When an XLSX or XLSM file is saved Excel needs to break it down into separate XML files, compress it and finally save it as XLSX or XLSM. The XLSB file format on the other hand is a binary Excel file. It resembles the old XLS file format which was also a binary file.
