Writing string blob to file (XLSX templating with Node)

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?

Solution

  • Figured it out:

    fs.writeFileSync(
    path.join(__dirname, 
    'templates', 
    'output.xlsx'), 
    data, 
    'binary', 
    function (err) { [...]

    The third parameter, 'binary', was key.
