Cannot set property 'options' of undefined

[MajorShaan]

a normal project just copied the readme example code

`const {convert} = require('xlsx-converter');

convert('id pass all core.xlsx').then(result => { // do something with the result console.log(result); });`

and got this error

this.options = opts || {}; ^

I also got this same error. The problem was that when calling 'convert' directly in this manner, 'this' is undefined because the require returns a class instance.

I was able to make it work like this:

const converter = require('xlsx-converter');

converter.convert( "filename.xlsx", { to: 'csv' }, ).then( result => { console.log(result); });
