JSON INPUT
YAML OUTPUT
Paste JSON on the left, pick a format, and get CSV or YAML instantly — entirely in your browser.
Need to turn an API response into a spreadsheet, or a config file into YAML for a Kubernetes manifest or CI pipeline? This JSON converter handles both common conversions instantly: an array of objects becomes a CSV with one row per object (nested fields flattened to dotted column names like address.city), and any JSON value converts to clean, indented YAML.
Like the rest of this site, conversion happens entirely client-side — nothing you paste is ever uploaded. For best CSV results, make sure your top-level JSON is an array of similarly-shaped objects; a single object converts to a one-row CSV, and a bare array of primitives converts to a single-column CSV.
