Debugging invalid JSON

Copilot Chat can identify and resolve syntax errors or structural issues in JSON data.

이 문서의 내용

When working with JSON data, you may encounter issues such as trailing commas, mismatched braces, or incorrect data types that make the JSON invalid. GitHub Copilot Chat can help you debug and fix these errors by suggesting corrections to fix invalid JSON.

Example scenario

Consider a scenario where an application consumes JSON data from an API, but the response fails to parse due to invalid formatting. You receive the error message:

Error: Parse error
----------------------^
Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '[', got 'undefined'

Below is the JSON data that caused the error:

{
  "location": "San Francisco",
  "current_weather": {
    "temperature": 18,
    "unit": "Celsius",
    "conditions": "Cloudy
  },
  "forecast": {
    "day": "Monday",
    "high": 22,
    "low": 15,
    "precipitation": 10
  }
}

Example prompt

Why is my JSON object invalid and how can I fix it?

Example response

Copilot might suggest that your JSON is invalid because it's missing a closing quote for the conditions value. Here is the corrected JSON:

{
  "location": "San Francisco",
  "current_weather": {
    "temperature": 18,
    "unit": "Celsius",
    "conditions": "Cloudy"
  },
  "forecast": {
    "day": "Monday",
    "high": 22,
    "low": 15,
    "precipitation": 10
  }
}

In this example response, Copilot's suggestions include fixing the closing quote for the conditions value, which resolves the JSON parsing error.
