AI result streams
Some tools save generated records and structured output one item at a time. A local reader helps you inspect the result without first moving it into a browser service.
JSONL and NDJSON on macOS
Read JSONL and NDJSON files on Mac
JSON Lines files are useful when an AI tool, log, or export writes one JSON object per line. Slate Viewer gives those local files a reader-first view, with the original source still close at hand.
Line-delimited data
JSONL and NDJSON keep one JSON value on each line
JSONL and NDJSON are names commonly used for the same line-delimited JSON pattern. They are different from one large JSON document: each line can hold a separate object, which makes them practical for result streams, exports, and logs.
Exports and logs
Line-delimited files can also appear in data exports and logs, where reading the content and checking the original source are both useful.
Source stays available
Use Preview to orient yourself, then switch to Raw when you need to see the exact text Slate Viewer opened.
A local reading workflow
Open, inspect, and make a small correction when the file needs one
Slate Viewer is designed to read the result before you choose a heavier tool. Start with a clear view, open Raw to verify keys and values, then use Light Edit only for a small local change.
It supports JSON and JSONL/NDJSON alongside Markdown, TXT/LOG, CSV, and TSV. It is not a cloud workspace, an AI assistant, or a JSON/CSV Quick Look extension.
