Errors when parsing TSV file

[jcbp]

Hi, thanks a lot for this project, it is really useful. I was getting some errors when importing my TSV file, and after debugging and making some changes in the file structure, I realized that it fails in the following cases:

• If the TSV file is generated from an FSL that is configured in a language other than English
• If the TSV file does not have any food records
• If the TSV file does not have any insulin records
• If the TSV file contains the national identification number (in my case is a DNI number from Argentina, I have no idea if this is standardized across all countries). This data is in the second line, before the header and after the patient name

Note: I use the FSL only for glucose measurement but I don't usually use it to record any other data.

Fragment from my TSV file:
