I’ve noticed that we often use Excel 97-2003 Workbook format (*.xls). As the name suggests, this file format came out in 1997 – 17 years ago. To put that into perspective, in 1997 Tony Blair became the British Prime Minister, Thailand’s economy crashed and Hong Kong was handed back to the Chinese.
Time to move with the times.
Can we start using the default Excel format (*.xlsx)? It’s 10 years old now and you’d have to be using Office 2003 to not be able to open it. This format is preferable as it has features that make it more useful in Office 2013.
Kind regards,
