Common questions about formatting, converting, and validating structured data.
Beautify adds indentation and line breaks for readability. Minify removes whitespace to reduce file size.
Yes. The editor highlights parse errors with line/column details so you can fix issues quickly.
Conversions preserve keys/values and arrays/objects where possible. CSV assumes a tabular structure; nested objects are flattened or stringified.
Yes — set comma/semicolon/tab, choose quote and escape characters, and include/exclude headers.
Standard JSON doesn’t allow comments; YAML does. For JSON with comments, use JSONC mode if available, or remove comments before parsing.
Yes. Enable Sort Keys to produce deterministic output, helpful in version control.
Depends on your device/browser memory. Multi-MB files work fine; hundreds of MB may require splitting or streaming.
No. Everything runs locally in your browser. Close the tab to clear the session.
Yes, UTF-8 text (including emoji) is fully supported. For other encodings, convert to UTF-8 before loading.
If your tool exposes schema options, paste a schema to validate structure and types. Otherwise, basic syntax validation is always on.
