How do I read a word list into an array

I´m making a learning tool, and I have a 6000 word list as a txt file, the words separated by newline.

1. How do I read it into an array? I know it should be in a Json format, but I can´t seem to find pointers as to how to edit the list to the correct format. (Hoping for a search and replace job on the list.)

2. Is searching a 6000 element array fast enough to check for the existence of a word?

By this I mean that when the user suggests a word I want to run it through the array using "contains value" to see if it is correct, without making the user wait.

Any help would be appreciated.

Have a read through the following thread to see if it's what you're after:

Thanks! Interesting read.

Am I correct in concluding that I need to get my list formatted like this:

{

"c2array":true,

"size":[6000,1,1],

"data":[ ["word1"],

["word2"],

["word3"],

["word4"]

]

}

and save the file as words.json to import it?

Looked for converters but nothing useful showed up. Guess I´ll try Word and Notepad to get it right.

What about the search speed? Anybody experienced these?

You can format your text file with notepad++ and regular expressions. If you want send me your file and i do that.
