Convert JSON Schema to SQL DDL

While doing research for an architectural change at work, I couldn’t find a nice npm library that let’s you create SQL tables from a JSON Schema. That’s how I decided to create one myself.

Convert JSON Schema to SQL DDL launched on May 15, 2025 with 10 votes, #2,185 of 7,905 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 1 year on.

In plain words

Convert JSON Schema to SQL DDL is a developer tool that transforms JSON Schema definitions into SQL table creation statements. Designed for developers and database architects, it addresses the gap in available npm libraries for this specific conversion task. The tool automates the process of generating SQL DDL from JSON Schema, streamlining database schema creation during architectural planning and development workflows.

    I built DDL to Data after repeatedly pushing back on "just use production data and mask it" requests. Teams needed populated databases for testing, but pulling prod meant security reviews, PII scrubbing, and DevOps tickets. Hand-written seed scripts were the alternative slow, fragile, and out of sync the moment schemas changed. Paste your CREATE TABLE statements, get realistic test data back. It parses your schema, preserves foreign key relationships, and generates data that looks real, emails look like emails, timestamps are reasonable, uniqueness constraints are honored. No setup, no…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

    We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship.
