How to Fix Invalid JSON Automatically (Without Writing Code)

JSON is everywhere — APIs, configuration files, logs — but invalid JSON is still one of the most common problems developers face.

Missing commas, extra trailing characters, or incorrect quotes can easily break your application.

Common Causes of Invalid JSON

Here are some typical issues:

• Trailing commas
• Missing quotation marks
• Incorrect brackets
• Copy-paste errors from logs

Why Manual Fixing Is Inefficient

Manually fixing JSON becomes painful when:

• The file is large
• The structure is deeply nested
• Errors are not obvious
