Frequently Asked Questions
Does it handle nested JSON?
Yes! Nested objects are flattened with dot notation (e.g., user.name, user.email). Arrays are converted to comma-separated values.
What if my JSON is not an array?
The JSON should be an array of objects. If you have a single object, wrap it in brackets: [{...}]
Are special characters escaped?
Yes, CSV special characters (commas, quotes, newlines) are properly escaped for Excel compatibility.
