</> Simplify Your Programming Logic

Lightweight developer tools for code generation, logic transformation, and visualization.

Tools

{}

JSON to Code

Generate Go structs, TypeScript interfaces, Rust types, and Java POJOs from JSON

If-Else Refactor

Transform nested if-else into switch-case, early return, or pattern matching

◉

Logic Flowchart

Visualize your code logic as interactive flowcharts

AI Prompt Builder

Build structured AI prompts with conditional logic visually

Regex & Cron

Test regular expressions and parse cron expressions instantly

All tools run locally in your browser. Your data never leaves your machine.

Why YZIF?

YZIF is a suite of free online developer tools that run entirely in your browser: convert JSON into Go structs, TypeScript interfaces, Rust structs or Java POJOs; refactor nested if-else statements into guard clauses; visualize logic as flowcharts; build structured AI prompts; and test regex patterns or cron expressions.

Because every conversion happens client-side, your data never leaves your machine - safe for proprietary code, internal configurations and anything under NDA. No signup, no rate limits, no telemetry on your input.

Typical use cases

Backend developers scaffolding models from API payloads; DevOps engineers validating cron schedules before deployment; AI engineers standardizing prompt templates across a team; anyone reviewing legacy conditionals that have grown too nested to reason about.
