Quote only strings and not numbers

[boldt]

I'm parsing the following file (quoted strings, non-quotes numbers):

name,age,city
"Chirstian",30,"Hamburg"

The option dynamicTyping detects name and city as strings and the age as number. If I unparse, I have two options.

Option 1) set quoteChar: '"', which results in:

name,age,city
"Chirstian","30","Hamburg"

Option 1) Skip the option `quoteChar, which results in:

name,age,city
Chirstian,30,Hamburg

I recommend an option onlyQuoteStrings, which applies the quoteChar: '"' only to strings, but not to numbers, similar to libre office save as CSV dialogue (option quote all text cells):

Thanks for your suggestion.

We will be happy to accept a pull request that implements it.
It should include a test scenario to ensure the behaviour is keep on future versions.

I implemented it that way, that onlyQuoteStrings always overrides the option quotes. I hope it fits.

Just a hint for other users: If the structure (columns) of your data is known beforehand you can use the quote option as an array of booleans (tested on https://www.papaparse.com/demo in browser console) to indicate the quoting
e.g.

Papa.unparse([['test', 1, 'test2'], ['test3', 4, 'test5']], {quotes: [true, false, true]})

which results in

"test",1,"test2"
"test3",4,"test5"
