PasteKit

Format, inspect, and convert structured data in your browser

Meet PasteKit

PasteKit is a browser-based toolkit for formatting, validating, and converting structured data and source text. Users paste content or open a file, choose a format, and inspect the result in adjacent input and output panes. It supports common formats such as JSON, YAML, XML, SQL, CSV, and Markdown, alongside numerous programming and configuration languages.

Tools include minification, key sorting, tree and table views, structural comparison, schema validation, and data repair. Processing happens locally in the browser, which makes it useful for developers inspecting payloads or configuration files they do not want to upload. Results can be copied or downloaded for further use.
