Homogenius – Packer/unpacker to reduce the size of JSON

In plain words

Homogenius is a packer and unpacker tool that reduces the file size of homogeneous JSON data by eliminating repeated keys and values. It is designed for developers who work with large JSON files containing repetitive structures. The current version removes duplicate keys, with plans to also eliminate redundant values in future releases.

From the sources

Homogenius is a packing/unpacking technique to reduce the size of homogenous JSON files. The main point of Homogenius is to prevent repeating keys and values in a homogenous JSON format, so this reduces the size of the JSON file. Currently we are in the first version of Homogenius and in this initial version, we are going to prevent repeating keys only. Further, we will alter Homogenius so it also prevents repeating values also. [ [{ "boo" : 1 }, { "nested" : [{ "boo_nested" : 1 }, { "foo_nested" : 1 }, { "bar_nested" : 1 }] }, { "bar" : 1 }], [ [ "val1" ], [ [ "val_nested1" ], [ "val_nested2" ], [ "val_nested3" ] ], [ "val2" ] ], [ 0 , [ 0 , 0 , 0 ], 0 ], [ 0 , [ 0 , 0 , 0 ], 0 ] ]…from homogenius.github.io

  GPT-JSON – Structured and typehinted GPT responses in Python2023 · github.com · ▲174

  Hey HN, I've been using GPT a lot lately in some side projects around data generation and benchmarking. During the course of prompt tuning I ended up with a pretty complicated request: the value that I was looking for, an explanation, a criticism, etc. JSON was the most natural output format for this but results would often be broken, have wrong types, or contain missing fields. There's been some positive movement in this space, like with jsonformer (https://github.com/1rgs/jsonformer) the other day. But nothing that was plug and play with GPT. This library consolidates…

  Robust LLM extractor for websites in TypeScriptMar 2026 · github.com · ▲72

  We've been building data pipelines that scrape websites and extract structured data for a while now. If you've done this, you know the drill: you write CSS selectors, the site changes its layout, everything breaks at 2am, and you spend your morning rewriting parsers. LLMs seemed like the obvious fix — just throw the HTML at GPT and ask for JSON. Except in practice, it's more painful than that: - Raw HTML is full of nav bars, footers, and tracking junk that eats your token budget. A typical product page is 80% noise. - LLMs return malformed JSON more often than you'd expect, especially with…
