How to use this tool

  1. Enter json array.
  2. Select Update result to view the result.
  3. Check the method and assumptions below before using the result.

The method, explained

Collect keys in first-appearance order across the objects, then write one CSV row per object. Quote cells containing commas, double quotes or newlines, and double embedded quotes.

A WORKED EXAMPLE

Objects with name and score properties produce a name,score header and one row for each object.

What to keep in mind

Flat objects only: nested objects and arrays are rejected. Missing values and null become empty cells. CSV is plain data; spreadsheet programs may interpret cells starting with =, +, − or @ as formulas. Do not open untrusted exports without reviewing them.

Reference: RFC 4180: comma-separated values

Common questions

Must every object have the same keys?

No. All discovered keys become columns, and missing values become empty cells.

Does this flatten nested JSON?

No. Restructure nested values explicitly before conversion to avoid silently losing information.
