Sometimes, we may run into the “unexpected token o” error when parsing JSON in our JavaScript app.
In this article, we’ll look at how to fix the “unexpected token o” error when trying to parse JSON in Our JavaScript app.
Fix the “unexpected token o” Error When Trying to Parse JSON in Our JavaScript App
To fix the “unexpected token o” error when trying to parse JSON in Our JavaScript app, we should make sure that we’re running JSON.parse on a valid JSON string.
For instance, instead of writing something like:
const obj = {
foo: 'bar'
}
console.log(JSON.parse(obj))
where we’re trying to call JSON.parse on the obj object, we should make sure that we’re calling JSON.parse on a valid JSON string.
For example, we write:
const obj = JSON.stringify({
foo: 'bar'
})
console.log(JSON.parse(obj))
to convert the object into a JSON string with JSON.stringify .
Then we can call JSON.parse successfully to parse the JSON string back into an object.
The console log should log:
{foo: "bar"}
Conclusion
