我没有知道的库，但是您可以使用node-xlsx解析excel文件，获取行并自己制作CSV。这是一个例子：
var xlsx = require('node-xlsx');var fs = require('fs');var obj = xlsx.parse(__dirname + '/test.xls'); // parses a filevar rows = [];var writeStr = "";//looping through all sheetsfor(var i = 0; i < obj.length; i++){ var sheet = obj[i]; //loop through all rows in the sheet for(var j = 0; j < sheet['data'].length; j++) { //add the row to the rows array rows.push(sheet['data'][j]); }}//creates the csv string to write it to a filefor(var i = 0; i < rows.length; i++){ writeStr += rows[i].join(",") + "n";}//writes to a file, but you will presumably send the csv as a //response insteadfs.writeFile(__dirname + "/test.csv", writeStr, function(err) { if(err) { return console.log(err); } console.log("test.csv was saved in the current directory!");});
