Receiving file without downloading

Hi, I'm wondering if it is possible to use this library to generate the excel file but not initiate the download? Looking to add the generated file to a zip file and download that instead.

Yep, you can get the file to an ArrayBuffer setting writeOptions.type to "buffer".

This is how its used in the Express demo https://github.com/LuisEnMarroquin/json-as-xlsx/blob/main/packages/demo-express/src/server.ts

const settings: ISettings = {
  writeOptions: {
    type: "buffer",
    bookType: "xlsx",
  },
}

 const buffer = xlsx(data, settings)
