JSON Array of Objects → CSV (Customizable Columns)
Take an array of JSON objects (typical API response) and convert it to CSV — but with control: pick which columns to include, reorder them, rename headers. Nested objects flatten via dot notation (address.city). Different from our basic JSON to CSV converter which just outputs all keys.
How to use the JSON Array of Objects → CSV (Customizable Columns)
Paste JSON array of objects. Click Parse JSON. The columns appear — toggle inclusion, rename headers. Pick delimiter and quoting. Copy or download the CSV.
Building a CSV with chosen columns
Converting a JSON array to CSV is easy; getting the right CSV is the hard part. A real export usually needs only some of the fields, in a particular order, under human-friendly header names — not every key the objects happen to carry, dumped in arbitrary order.
This gives you that control: parse the array, then choose which columns to include, drag them into the order you want, and rename the headers before exporting. Nested objects flatten via dot notation. When you simply want every field out with no fuss, the plain JSON to CSV converter is the quicker path; this tool is for when the shape of the output matters.
Common use cases
- Pick columns — export only the fields a report needs, not the whole object.
- Reorder — arrange columns in the sequence a downstream tool expects.
- Rename headers — replace raw keys with readable column titles.
- Trim an API dump — drop internal fields before sharing the data.
- Match a template — shape a CSV to fit an existing import format.
