Similar tool for JSONL files: I built JSONL Viewer Pro after repeatedly crashing VS Code trying to inspect multi-GB training datasets and IoT device logs with nested objects.

Native Mac/Windows app with multi-threaded parsing (simdjson), automatic nested object flattening, and handles 10M+ rows instantly.

For HN: Use code HN100 for free access

Built with C++ for native performance (~6MB app, not Electron).

Would love feedback from folks working with large JSONL files.

Super quick feedback - opening that link on my phone shows me two options next to each other, seemingly with the same name / description (followed by …) and same pricetag. I had to turn my phone sideways to see that there is a windows and a Mac version.

I think you can afford the extra characters to show the whole page in portrait mode. (iPhone 16 pro Safari)

I will change the description. Thank you!

Quick update: Mac ZIP had a corruption issue that's now fixed. Anyone who downloaded in the last few hours - please re-download!

Also just added a Data Plot feature for visualizing numeric columns.

Thanks to everyone who reported the issue!
