Practical guide

Validate large API responses, locate invalid lines, search and replace fields, inspect Code, Tree, Form or Table views, then download JSON or XLSX.
What is JSON Beautify and Viewer?
This tool streamlines workflows such as inspecting large api responses and logs and locating an invalid json line in one place.
Common uses
- Inspecting large API responses and logs
- Locating an invalid JSON line
- Turning JSON arrays into tables and Excel output
- Searching and replacing fields in bulk
Practical examples
Collapse nested objects, navigate matches and inspect problematic fields in context.
The tool selects the meaningful record array, builds columns and exports XLSX instead of flattening the wrapper object.
Missing commas, quotes or brackets are reported and highlighted in the input.
Frequently asked questions
Is JSON sent to the server?
No. Formatting, views, search and downloads run in the browser.
Why can very large JSON slow down?
Parsing and rendering use browser resources; the tool uses virtual rendering for large data.
Which data does Table view use?
It prioritizes the most meaningful array of record objects and avoids forcing wrapper status fields into the table.
