On 22 November 2017 we will change the format of all current Excel from .xls to .xlsx.
A file with the XLS extension is a Microsoft Excel 97-2003 Worksheet file. Later versions of Excel save spreadsheet files in the XLSX format. This change in format is required as the XLS format is becoming obsolete.
Initially we will not change the format of the Excel files that are no longer current or updated, e.g. discontinued statistics. We will look to apply the format change to these files over the next few months.
We are not changing the presentation of the data in the Excel files.
