Outcome and workflow

Validate, browse, and edit JSON content with millions of lines

Large files need more than a larger text box. JSONBuddy combines a large-file viewer, targeted editing, fast text search, well-formedness checks, JSON Pointer evaluation, formatting, and streaming schema validation so each operation can use an appropriate mode.

Open and browse very large files

Use the large-file view to inspect multi-gigabyte JSON or text documents while loading only the content needed for the current view.

Jump directly to a finding

Move by line number, search for text, or resolve the JSON Pointer path reported by validation to reach the relevant value without scanning the complete file.

Edit, format, and convert

Make focused corrections, pretty-print or minify large input, and continue into JSON/XML conversion when the result needs a different representation.

Capabilities by workflow

Choose viewing, editing, or streaming validation

Standard large-file tools

Open and browse files, check JSON well-formedness, format large input, and run command-line server or batch tasks.

Focused editing tools

Edit large documents and use the validation debugger while developing and correcting schemas.

Streaming validation tools

Apply the large-data JSON Schema validator from the desktop or command line when the document should not be handled as an ordinary in-memory editor task.

Edition names and entitlements need release confirmation

The existing page separates Standard, Plus, and Large Data capabilities. Verify the current package names and exact entitlement boundaries before publication.

Performance evidence

Test the current build with representative data

The established page records SSD loading and streaming-validation examples for 238 MB, 484 MB, and 811 MB documents on a mid-range desktop. Preserve the useful methodology, but rerun every result against the release candidate.

Record CPU, memory, storage, operating system, and product version.
Identify the file, schema draft, schema complexity, and expensive keywords.
Separate editor loading time from streaming validation time.
Publish measurements as examples, not universal limits.
