how to parse csv from github?

Question

jQuery.ajax({
    url: \"https://raw.githubusercontent.com/CSSEGISandData/COVID-19/master/csse_covid_19_data/csse_covid_19_time_series/time_series_19-covid-Confirmed         


        

Answer 1

Parsing CSV is not always as simple as doing "...".split(','). And the file here is a perfect example of that. Some fields contain a ,, and thus are wrapped in quotes.

I suggest using Papa Parse which will handle that for you. I've used it many times before, it saved me a lot of headaches!

$.ajax({
    url: "https://raw.githubusercontent.com/CSSEGISandData/COVID-19/6eae5b65a32b679efacf95a2867648330f83a871/csse_covid_19_data/csse_covid_19_time_series/time_series_19-covid-Confirmed.csv",
    success: function(csv) {
        const output = Papa.parse(csv, {
          header: true, // Convert rows to Objects using headers as properties
        });
        if (output.data) {
          console.log(output.data);
        } else {
          console.log(output.errors);
        }
    },
    error: function(jqXHR, textStatus, errorThrow){
        console.log(textStatus);
    }
});
