xlsx 's direct dependencies. Data on all dependencies, including transitive ones, is available via CSV download.SheetJS, also known as 'xlsx', is a comprehensive, community-maintained JavaScript library that allows you to work with various spreadsheet formats. It's particularly useful for parsing spreadsheets and extracting meaningful data from them, as well as generating new spreadsheet files. This library offers a solution for processing a myriad of spreadsheet data formats, enabling simple data extraction from almost any complex spreadsheet and generating new spreadsheets that are compatible with both legacy and modern software.
To make use of the xlsx package, you need to install it first using npm (npm install xlsx). Then you can import and use it in your JavaScript file. There are different methods to extract and process data depending on where the spreadsheet data is coming from. Here are two simple examples of how to use the library:
var XLSX = require("xlsx");
var workbook = XLSX.readFile("test.xlsx");
var url = "http://oss.sheetjs.com/test_files/formula_stress_test.xlsx";
/* set up async GET request */
var req = new XMLHttpRequest();
req.open("GET", url, true);
req.responseType = "arraybuffer";
req.onload = function(e) {
var workbook = XLSX.read(req.response);
/* DO SOMETHING WITH workbook HERE */
};
req.send();
