Thanks. Amazing explaination. For those looking for multiple sheet writing, here is the code snippet.

const exportToCSV = () => {
const ws = XLSX.utils.json_to_sheet(sheet_data1);
var ws2 = XLSX.utils.json_to_sheet(sheet_data2);
const wb = XLSX.utils.book_new();
const sheet1 = XLSX.utils.book_append_sheet(wb, ws, "Name of Sheet1");
const shee2 = XLSX.utils.book_append_sheet(wb, ws2, "Name of Sheet2");
XLSX.writeFile(wb, "Output_filename.xlsx");
};

Thanks for the article but I don't think you need 👉file-saver - library

XLSX.writeFile(wb, 'sheetjs.xlsx') does the job...

Hi, I'm very intersting with your solution but how can I export columns that I want to export them. Example: I have id, displayID, name, age which of them are columns and I just want to export data from name, age.
Thanks for your supporting.

You need to change place where I am retrieving data from server. Add this code and analyze what I did. I put comments.

 React.useEffect(() => {
    const fetchData = () => {
      axios
        .get("https://jsonplaceholder.typicode.com/posts")
        .then((response) => {
          let newArray = [];

          response.data.map((item) => {
            // here i am  extracting only userId and title
            let obj = { userId: item.userId, title: item.title };
            // after extracting what I need, I am adding it to newArray
            newArray.push(obj);
            // now  I am adding newArray to localstate in order to passing it via props for exporting
            setData(newArray);
          });
        });
    };
    fetchData();
  }, []);

P.s
Regarding code style, I did simple solution in order to give you idea. Obviously, you can do code more beautiful and shorter.

Hi, if to say data in json being exported is a boolean from, i tried writing a function to convert it from true/false to "yes" /"no". this is the result "TypeError: js.forEach is not a function" can you help explain why and what do you think i can do.

1) Download this repo github.com/jasurkurbanov/react-api...

2) Inside App.js replace useEffect to the code below

React.useEffect(() => {
    const fetchData = () => {
      axios.get('https://www.arbeitnow.com/api/job-board-api').then(postData => {

        // reshaping the array
        const customHeadings = postData.data.data.map(item => ({
          "Company Name": item.company_name,
          "Location": item.location,
          "isRemote": item.remote ? 'Yes' : 'No'
        }))

        setData(customHeadings)
      })
    }
    fetchData()
  }, [])

3) Result

Hope it helped to you)

I wonder if it's possible to send styled excel? I mean at least to adjust columns width to fit data. Also it would be nice to make table borders like this:
