Load and use xlsx in browser env [help wanted]

[iabukai]

I have a NuxtJs/Vuetify application and I try to use my xlsx template from my static resources then add data and then save the file with the updated data.
I tried this :

const workbook = new Excel.stream.xlsx.WorkbookReader({ filename: '/static/template.xlsx' })
      workbook.xlsx.writeBuffer()
        .then(buffer => saveAs(new Blob([buffer]), `${this.asd.date} ${this.asd.place} .xlsx`))
        .catch(err => console.log('Error writing excel export', err))

But he downloaded xlsx was corrupted.
saveAs coming from : import { saveAs } from 'file-saver'

Did you attempt to use (new Excel{}).xlsx.readFile(/*...*/).then(/*...*/); ? I suppose, that your code didn't read any data before writeBuffer.
