Generators and converters

Generators produce values from rules: random or time-ordered UUIDs, cryptographic hashes, color values across formats, TypeScript interfaces from a JSON sample, Markdown tables from CSV, JIRA or Confluence markup from Markdown, the full favicon set from an SVG, formatted Terraform tfvars from messy input, structured request data from a curl command. None of them require a sign-up; none of them upload your input; all of them give you a result you can copy straight into a file or a config.

The use cases vary by trade. A developer bootstrapping a project: UUIDs as primary keys, hashes for cache keys, TypeScript interfaces from API responses. A designer translating a hex color into HSL for a CSS variable. A technical writer pasting a CSV into a Markdown PR description. A site owner generating the favicon variants the modern web actually uses (16, 32, 180, 192, 512).

What makes a good generator: predictable output, sensible defaults, the ability to preview before copying. The tools below aim for that bar. Where input ambiguity exists (single-quoted vs double-quoted strings, comma vs tab as a delimiter, RGBA vs RGB), the tool exposes a setting and explains the difference rather than guessing for you.

If a generator you would use is missing, the about page explains how to suggest one. The catalog grows as new tools ship.
