I have data in txt or excel,csv format locally. Can I convert the data into json format and read it directly with echarts?
some of the methods I found on the Internet are loaded with ajax, or jquery. I tried without success. Checked as if to set up a local server to request data.
you can use the data in .js format in JOSN format and then use JQ's ajax to request the path to your local data file.
