How to use NDJSON Validator & Normalizer

Validate newline-delimited JSON record by record and normalize each value onto one line.

1. Paste, type, or drag and drop a supported text file into the input area.
2. Review the input and the clearly labeled output behavior.
3. Select “Run tool” or press Ctrl/Command + Enter, then copy, download, or move the result back into the first input for another pass.

What the result means

Valid normalized NDJSON with one compact JSON value per line.

Privacy and safety

This utility is loaded as browser code and processes your input only in this tab. OmniCastConverter has no upload endpoint and never stores your content, filenames, tokens, or secrets. Generated markup and code are shown as inert text and are never executed.

Limitations

• Each nonblank line must be a complete independent JSON value; multiline records are rejected.
