How can I store a large amount of values into an array?

So I’m making a Japanese symbol flash card program, as there are a lot of symbols in the alphabets. Hiragana alone has 71 symbols, and so I’m storing their spellings into an array, but I don’t want to write every element of the array into the script, that feels very innefficient.

Is there a way I can store them in a file such as Notepad or any other way? Or is writing every element out the best way?

you should be able to use XML or JSON to create a file or spreadsheet table that you can use with the correct character font of course and import it that way. There are a ton on tutorials in the rpg game world for doing things with items in database tables. Start there.
