UPDATED version of this tutorial available here
CREATE AND INSTALL
Create new react project
npx create-react-app react-data-to-excel
Now start project
npm start
Project successfully created.
Lets dive into installing neccassry libraries for our project. Install these three libraries.
npm install xlsx file-saver axios --save-dev
πxlsx - library for parsing and writing various spreadsheet formats
πfile-saver - library for saving files on the client-side
πaxios - promise based HTTP client for the browser and node.js. We will use it for fetching data from server
UI AND LOGIC
Create a component namely ExportToExcel.js
import React from 'react'
import * as FileSaver from "file-saver";
import * as XLSX from "xlsx";
export const ExportToExcel = ({ apiData, fileName }) => {
const fileType =
"application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;charset=UTF-8";
const fileExtension = ".xlsx";
const exportToCSV = (apiData, fileName) => {
const ws = XLSX.utils.json_to_sheet(apiData);
const wb = { Sheets: { data: ws }, SheetNames: ["data"] };
const excelBuffer = XLSX.write(wb, { bookType: "xlsx", type: "array" });
const data = new Blob([excelBuffer], { type: fileType });
FileSaver.saveAs(data, fileName + fileExtension);
};
return (
<button onClick={(e) => exportToCSV(apiData, fileName)}>Export</button>
);
};
Sample data we will get from https://jsonplaceholder.typicode.com/posts
App.js
import React from 'react'
import axios from 'axios'
import './App.css';
import {ExportToExcel} from './ExportToExcel'
function App() {
const [data, setData] = React.useState([])
const fileName = "myfile"; // here enter filename for your excel file
React.useEffect(() => {
const fetchData = () =>{
axios.get('https://jsonplaceholder.typicode.com/posts').then(r => setData(r.data) )
}
fetchData()
}, [])
return (
<div className="App">
<ExportToExcel apiData={data} fileName={fileName} />
</div>
);
}
export default App;
Start project
npm start
Once it successfully started. You can see one button. By pressing this button you download excel file with data filled from https://jsonplaceholder.typicode.com/posts
Output
Excel File

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
πfile-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.
Screenshot after exporing data. Checkout
dev-to-uploads.s3.amazonaws.com/up...
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 below3) Result
Hope it helped to you)
How can I put custom headers?
Can you show where you want to add headers ?
in the first row a title and in the second row are the column headings
Sorry I did not get, what you mean. If it possible please provide some screenshots , in order to figure out.
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:
Nice idea, thank you. I need to do research about your idea
Thank you buddy
Any update?
