Mind you, Microsoft already had an earlier very capable XML spreadsheet format that was much easier to parse, SpreadsheetML. Back in the early 2000's I wrote readers and writers for it and made pretty heavy use of the format at my job at the time. The biggest problem with SpreadsheetML was that it expected the extension to be .XML - Microsoft had some sort of magic that would still associate the files with Excel on Windows but it wasn't super reliable. We started using .xls but after an update Excel started barking about files with the wrong extension. https://en.wikipedia.org/wiki/SpreadsheetML |
