FAQ
Q: Is my data secure?
Yes! All JSON to CSV conversion happens entirely in your browser using client-side JavaScript. Your data never leaves your device and is not sent to any server.
Q: What format should my JSON be in?
Your JSON should be an array of objects with consistent keys. For example: [{"name": "John", "age": 30}, {"name": "Jane", "age": 25}]. Single objects are also supported and will be converted to a single-row CSV.
Q: Can I convert nested JSON objects?
Yes! Nested objects will be flattened and included in the CSV output. Nested properties will be represented with dot notation in the column headers.
Q: What if my JSON objects have different properties?
The converter will include all unique properties as columns. If an object is missing a property, that cell will be empty in the CSV output.
