kandi X-RAY | xlsx-template Summary
This module provides a means of generating "real" Excel reports (i.e. not CSV files) in NodeJS applications. The basic principle is this: You create a template in Excel. This can be formatted as you wish, contain formulae etc. In this file, you put placeholders using a specific syntax (see below). In code, you build a map of placeholders to values and then load the template, substitute the placeholders for the relevant values, and generate a new .xlsx file that you can then serve to the user.

QUESTION
I'm using the xlsx-template library to generate Excel documents. I'm recreating the example from the github readme and I'm stuck on the first step - the standard templating function returns a 'string blob' representing the excel file.
How do I write a string blob to the file system in node?
