Question about streams and accessing file content

I'm trying to create an Excel worksheet with Node.JS and be able to upload it to Dropbox using their API. This is how I create the Excel spreadsheet.const Excel = require('exceljs') const workbook = new Excel.Workbook() workbook.addWorksheet('My Worksheet') const myWorksheet = workbook.getWorksheet('My Worksheet') myWorksheet.columns = [ { header: 'Name', key: 'name', width: 32 } ] myWorksheet.addRow({ name: 'John Doe' }) workbook.xlsx.writeFile('my_worksheet.xlsx') .then(() => { console.log('Worksheet created successfully') }) This works great, but I don't want to save it to a file. I would like to know a way to save the contents of the file in a variable/stream? (I'm a beginner at node). The ExcelJS docs mention something about using streams but didn't say anything about accessing the file content.This is how I upload a document using Dropbox's API.const Dropbox = require('dropbox') const fs = require('fs') const dbx = new Dropbox({ accessToken: '' }) fs.readFile('./test.txt', 'utf8', (err, contents) => { if (err) console.log(err) dbx.filesUpload({ path: '/test.txt', contents: contents }) .then((response) => { console.log(response) }) .catch((err) => { console.log(err) }) }) Thank you.
