I'm running this application locally. So it started on localhost 5173. This is actually the interface. So here you can create Excel spreadsheet directly in the browser.

You can fill out the columns and run the rows here. So it's sim similar to the Microsoft Excel but it's available directly in the browser. So I built out this application in ReactJS. I've given the source code. If you want you can directly purchase it. So once you purchase it you will get a zip file from Google Drive automatically. [snorts] So this is actually the overall directory structure. Every component is divided into its appropriate TypeScript file here. As you can see, each every component is divided. So now to run this command line. Simply type the command npm rundev. So this will start the development server at localhost 5173. So I'm just running this application right here. So after you fill out your necessary information, necessary information, so it's very simple. information. After that you have the option you can click on the file button and [snorts] you can actually download this as a CSV file, Excel file or JSON file. So we have all these three options available.

You can even export this as an Excel file. written is directly exported. So this is actually the full Microsoft Excel spreadsheet clone that I developed in ReactJS. If you are interested, I've can directly purchase it. So for building this, we are using the latest version of React. So once you get the source code, you will able to get actually modify the source code or add additional features on top of it as well. So [snorts] this is a full directory structure. We are also using React router, React spreadsheet as well. These are some of the third party libraries that we are using for this. We are using Daisy UI for the user interface. This is a complete application. You can even save your work as well. Just click the save button and it will save. And uh so everything will display right here.
