How to Fetch Selected Data from Excel File in React JS | React XLSX
How to fetch selected data from excel file in react js? How to read excel file in react js? I published a tutorial earlier that demonstrated how to fetch and display data from excel file using react js. Someone asked, "If you only want to access data from one column. How to do it?" So here it is.
The handleFileUpload function is triggered when a file is uploaded. It reads the uploaded Excel file and converts its content to JSON format. The JSON data is then stored in the 'state variable' data.
We created the table headers. We are using the keys of the first JSON object in the 'data array' to create the column names. And we are iterating over each row in the data array to display it in the table. Each row is represented as a JSON object. The values of the object are extracted and displayed in the table cells. Pretty straight forward.
So what if we want to fetch data from a single column? We don't need all data in table head. So I will use the column name. And then we will replace all of the iteration with the actual key name of the column we want to display. This will render only the selected column in the table. So this is how you fetch a single column. It is easier than iterating and displaying everything.
