Below please find out the piece of the code used to export weather data from Mathematica to Excel. When I used it on the Mac it never converts it to Excel spreadsheet. Where is the mistake please?
mydataMinTempKTaMia = WeatherData["KTMB", "MinTemperature", {{2005, 1, 1}, {2012, 12, 31}, "Day"}]
Export["/Users/davidquesada/Documents/Research-SRI-Projects/SRI2017/MinTempKTaMia.xlsx", mydataMinTempKTaMia, "XLSX"]
I tried with "xls" also and it said invalid format, cause I changed into "xlsx"
