Since version 0.16.5, th following code returns a null worksheet:
XLSX.utils.json_to_sheet([], {header: columns})

Is it now working as it is wanted? If so, how could we create an empty worksheet? In my case it is expected that sometimes the data is an empty array. And an empty worksheet only with headers is expected.

It would be great to have the option "skip N lines", since CSV files often contain not commented headers. Can this be implemented?
For example:

This is a data file generated by some old software.
Next line will contain a headers of parameters.
Temperature, Humidity, Voltage
