Easily convert your JSON data into a clean, well‑formatted CSV file. Supports nested objects by either flattening key paths or stringifying them as compact JSON. No sign‑ups, no uploads—all processing stays local in your browser.
The tool expects a top‑level JSON array where each element is an object. If the structure is different (e.g., a single object or a primitive), an error message will explain what was found.
You can switch between two modes: Stringify turns nested values into escaped JSON strings inside a single cell; Flatten expands nested keys using dot‑notation (e.g., address.city) and creates separate columns for each leaf field.
Yes, a dropdown lets you choose between comma (,), semicolon (;), or tab. The CSV escaping rules adjust automatically.
