Custom JSON file invalid

Hi, I'm trying to load a whole bunch of locations into a map in my app, but I don't want to add each one individually, so I created a JSON file to load them all at once. I formatted the script correctly as far as I can tell, and JSONlint says it is valid, but when my app tries to load the file it says there was an error in the JSON. I've compared the code to other working JSON files from other apps but still can't find my mistake! I'm copying the link to the file below, hopefully someone can figure it out! https://www.buzztouch.com/applications063014/JA12B71DE7F5405C528834CCC/documents/JSON%20for%20wifi%20locator.txt Thanks in advance! P.S.- I'm very new to app making so this may have a very nooby mistake. :D

Most likely the apostrophe is the problem. Make a copy of your JSON file. Then take it out of places such as Wolfe's Pond Park. Try the new JSON file to see if the error goes away. Then try to insert just one apostrophe, but precede it with a \ character. For example, Wolfe\'s Pond Park. -- Niraj

I cannot remember if the \ will let you escape out of that error while still keeping your apostrophe in the words. I did some research and had a surprise -- I had previously answered this same question about apostrophes! This was my advice back then: If you need a single quote inside of a string, since \' is undefined by the spec, use \u0027 see http://www.utf8-chartable.de/ for all of them So ... instead of the apostrophe or the single quote character, try to put \u0027 in it's place. -- Niraj

One more tip ... After fixing the JSON file, remember to do a Clean and Run to start fresh. You might also have to reset the Simulator to erase any cached JSON files. -- Niraj

Could I use a curly apostrophe in places like "Wolfe’s Pond Park"? I know from troubleshooting my code earlier that those are not recognized to close the line.
