PHP fwrite “.xlsx format or extension is not valid” local server

问题

I am trying to write data into an excel file. I execute the code, but when I then try to open the excel file, I am getting an error that states that the format or the extension are not valid. This is my first time working with excel files on PHP.

Here is my code:

$e = fopen("Test.xlsx", "w");
fwrite($e, $balances['XVG']['onOrder']);
fclose($e);

Excel 2013 version:

Does anyone knows what could be wrong? Thank you.

You can also use Microsoft's XML format for Excel:

https://en.wikipedia.org/wiki/Microsoft_Office_XML_formats

To create a one row spreadsheet with a header, you would write the following XML to a file:

$xml = <<<END_XML_ZZ
    <?xml version="1.0" encoding="UTF-8"?>
    <?mso-application progid="Excel.Sheet"?>
