Making Data Exports Easier with SheetJS and React JS

If you work with data, you know that exporting it from one platform to another can be a challenge. However, with the help of SheetJS and React JS, this process is made easier. SheetJS is an open-source JavaScript library for manipulating spreadsheets in the browser (part of the suite of libraries called the “JS-XLSX” library) while React JS is a JavaScript library used to build user interfaces. Let’s take a look at how these two powerful tools can be used together to export data.

Prerequisites:

You should have basic knowledge of React Js, creating a React App, and running a react app.

How SheetJS Works

SheetJS allows developers to convert table data between different spreadsheet formats such as XLSX (Excel 2007+ XML), XLSB (Excel 2007+ Binary), XLS (Excel 97–2004 Binary), ODS (OpenOffice), Flat ODS (OpenOffice), SpreadsheetML (Excel 2003). It supports both client-side and server-side operations, so you can use it on both frontend and backend applications. To get started with SheetJS, you either download the file from GitHub or npm. Once you have installed the file, you will be able to access all of its utility functions and features.

One of these features is parsing data from any given source into a format compatible with other applications or libraries — such as React JS. This makes it easy to move data from one platform to another without having to manually input everything each time. Furthermore, SheetJS also allows developers to write their own custom functions which greatly increases its versatility and usefulness when dealing with complex data sets.

Using React JS with SheetJS

Now that we understand what Sheetjs offers us let’s take a look at how we can utilize React JS along with our data export task. The first step is setting up our project folder structure using create-react-app so that we have all our necessary files in place for development purposes.

Create a table using React JS

Create a basic table to display the list of items and their prices. Include the code below in your App.js and App.css file

Now that we have our library installed and imported correctly, let’s move on to actually exporting data into an Excel file!

Exporting Data with Sheet JS
To export data with sheet js, we need an array of objects representing each row of data we want to be exported, specify the name of the file, the data to be written, the options such as the type of the file, and write the data to a file in excel format.

The array of objects should look something like the one in our data.js file. For each key-value pair in the object, a new column will be created in our spreadsheet containing the corresponding value for each row. Once we have our array of objects ready, we can pass it off into our workbook object via its write method like so writeFile(wb, "items.xlsx") . This will write all of our data into a new spreadsheet and finally, the data will be saved on your computer/device using the file name items.xlsx. All this can be done with the exportData function below

There are different sheet js utility functions but in the course of this article, we will be focusing on the ones listed below.

writeFile

writeFile : This determines the format in which your data will be saved. The method packages the data and attempts to save the new file.

And finally, add an onClick event to the Export button that will call the exportData function when the button is clicked to download the file.

Your final code should look like this.

You can now click on the button to export the data. Your excel sheet will look similar to the one below.

Conclusion

Using SheetJs and React JS together makes it easier to export large amounts of structured data quickly and easily across multiple platforms without losing accuracy or quality in the transfer process due to their interoperability functionality. These two powerful tools enable developers to manipulate spreadsheets in the browser quickly while still maintaining high levels of accuracy. This combination ultimately allows for more efficient development processes when dealing with complex datasets making them invaluable assets when working on projects involving large amounts of data exports. So if your project involves moving large quantities of structured information from one platform to another consider using SheetsJs alongside React Js or any other JavaScript library(Vue Js, Angular, Svelte) — It could save you both time and energy!
