24 alternatives to Merge JSON Files
It’s fast, free, and doesn’t require any sign-up. Just upload your files, and it merges them into one clean JSON output. I made this because I kept running into small but annoying JSON merging tasks while working on side projects — especially when dealing with API responses, config files, or datasets. Most existing tools were either CLI-only, full of ads, or had weird size limits. So I built my own.

JSONBason▲15I've been at it again, just sharing my simple JSON data inspection tool, love webdev and single page apps, this one took 4 days and was a lot of fun.

Made with love for the fun of it, no ads, no paid anything, it's totally free. Please only send in sanitized/test data only, this is meant to help make webdev a bit easier and more fun.…

Hi all, I built this tool when I needed a simple LocalStorage-esque database for a client project, and figured others might want something similar. Basically turns your JSON into a query-able, hosted database in seconds. You can read/update/delete JSON files by path, just like you would in Javascript. So, something like get(”users[7].address”) And while we’re at it, I also built a simple file storage service where you upload a file and it gives you the URL back. A lot of my (and other devs friends') side projects will never require more data than a JSON file can handle. Yet we…
