I know that the value is "text:u'NULL'" but if I try to write an if function which compares a variable which I have given the same value, it does not recognise them as the same. (Just to explain my spreadsheet has the value Null in the cell I am referring to but using XLRD it reads this as "text:u'NULL'" which is fine) I have created a test example of what I am referring to as this is hard

问题 I have an excel spread sheet (.xls) that contains a time column. The time is displayed in Excel as minutes:seconds.tenths of seconds. Such as "50:59.2" "50:59.4".
