After two years of improvement, I think it's time to share it with you all. Here’s a quick overview: - Common features include validation, formatting, minification, and more. - Visualize JSON in a graph or table view. - Structured comparison with fallback to text comparison. - Navigate though JSON using JSON pointer. - Supports jq. Would love to hear the community's questions, thoughts and comments!

pg_jsonschema is a solution we're exploring to allow enforcing more structure on json and jsonb typed postgres columns. We initially wrote the extension as an excuse to play with pgx, the rust framework for writing postgres extensions.

We built this in a day to help save some time internally and wanted to share as others might find it useful for managing structured output schemas. There’s a few other tools out there - but none had exactly what we needed! Key Features: 1. Two-Way Editing: Paste in an existing JSON schema and edit it within the UI 2. Data-Type Validations: add validations to fields 3. Local Storage & Version History: track your edits, don’t lose changes Link: https://schematools.herondata.io Source Code: https://github.com/heron-data/schema-tools

Hey HN! Erik here from banana.dev We’ve trained a small(ish) language model on structured extraction, and today we’re launching a playground for it at https://anythingtojson.com. Give it a try! This model continues our work on structured generation, following last week’s launch of Fructose[1], a python client for strongly-typed LLM responses. There seem to be two distinct halves of the problem intended to be solved by Fructose and structured generation: 1. the reasoning ability of the model, such as performing chain of thought, creative acts, and natural language tasks. In a way,…
