Encountering an issue while fetching information from a JSON file using JavaScript

I am encountering an Uncaught SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data

let mydata = JSON.parse("file.json");
console.log(myJSON)

Here is a sample of the JSON file's data:

[[1,1,0,1,1,0,0,0,1,1,1,1,1,1],
[1,0,0,1,1,0,0,0,1,1,1,1,1,0],
[1,0,0,1,1,0,1,1,1,1,1,1,1,1],
[1,0,0,1,1,0,0,0,1,1,1,1,1,0], .... etc]

Answer №1

When using JSON.parse, make sure to provide an actual JSON string and not just the file name. For example, use

JSON.parse('{ "a": "b" }')

. If you are working in Node.js, you can utilize the fs module to read the file and parse it. In a browser environment, you will need to use a file input to read the file before parsing it.
