You can use:

 NSString *jsonString  = [NSString stringWithContentsOfFile:yourFilePath encoding:UTF8StringEncoding error:nil];

Here:

yourFilePath is a NSString which contains the exact path to the .txt file.

You get the file content in jsonString variable, you need to save that string to database.

Refer NSString class for more

I don't know where you are having trouble, but it seems like you haven't gotten a JSON object from your string yet, so I will let you know how to do that. If you need to know how to create and store data in a database, then you need to make a new question and say that you got JSON data but are having trouble storing it into a database (at least make an effort to try to do it though).

You can use NSJSONSerialization to get an object out of your string (the NSData version of your string, at least). It will look like this:

NSDictionary *jsonDic = [NSJSONSerialization JSONObjectWithData:yourData options:kNilOptions error:nil];

If it doesn't work then your JSON is not valid. Validate it at http://www.jsonlint.com
