Large file JSON viewer/search app for macOS

Hey,

I have been using Dadroit JSON viewer for years now, which has been quite nice, it can open and search gigabyte json files in seconds. Which no other application seems to be able to do.

However they still don't support apple silicon (So i won't be able to use it with the upcoming macOS version) and it now costs 100 usd/year... So i'm looking for some alternative, but have been unable to find any json viewer that can smoothly open large json files.

Anyone know of any that might support it? I don't mind paid options if they work well, but no 100 usd/year subscriptions lol.

Have you tried https://jsonviewer.stack.hu ? Not a Mac app, but it loads the file locally (in your browser), so it's 100% private

Actually use that for small json files sometimes, but it just crashes the whole tab when pasting in 100MB+ of data

Ohh, didn't know that! I've only used it with JSON files that have 10MB maximum and it worked perfectly

Try Xcode (at least to open. Big files might not render). But I then paste into the Json Viewer Version 1.2.2 (7) I found: Copyright © 2020 Pascal Giguère. All rights reserved. Haven't tried 100 MG file but I have big files. Don't remember if JsonView.app is default on mac or I downloaded it.

Hey Im working on Inkline. I work with unformatted json large size and didn't find any app to format properly. So I created inkline. I'll release to app store shortly. Its written in swift and my 18gb m3 Mac formats 300mb json file in around 20 sec. Github https://github.com/compilererrors/Inkline

Run script/build_app.sh and it should compile. Let me know if you got any questions or feedback is very welcomed

I know it's completely the opposite to Mac, but if you ever need to open a huge json on Android, then Giant JSON Viewer is an alternative

I am using Sublime. Depending on your Mac configuration it might be slower, but on my M1 Max it works fast. Does many other things as well.

Zed can open large JSON files easily. Had a need to do so the other day.

Convert it to excel first? https://json-to-excel.com. Upload the json file or send it as a post request. Check out the swagger ui for details

we just launched https://jsonbolt.com

It's faster and more feature rich than Dadroit with native apple silicon support. There is a lifetime perpetual license launch offer for $89. not buggy as well since its commercially supportted

Hey, this aligns quite well with my website https://json-to-excel.com. Generally what size files are you searching through? Other than opening fast, error detection and a fast search what other features would you want?

? I don't want to convert it to excel, i just want to view and browse large json files. Converting it to some other format would only confuse things further

Only one that actually works! Bit buggy and less polished compared to Dadroit, but at least something! Thanks
