Common questions
What JSON shape converts best to CSV?
An array of objects, where each object becomes a row and each key a column header — for example [{"id":1,"name":"Ana"}].
How are nested objects handled?
Nested objects are flattened into dotted column names such as address.city. Arrays inside a record are written as JSON text in a single cell.
My JSON is rejected — how do I find the error?
Paste it into JSON Beautifier, which validates the syntax and points to the line with the problem (often a trailing comma or unquoted key).
