Softaken Adds JSON Validator to Browser-Based Online Tools Lineup

Softaken Software today announced the availability of a free online tool, JSON Validator, which validates JSON code for syntax errors and provides the exact location of the errors in the user’s web browser. This is for developers and API testers who need a quick way to confirm that a JSON payload, configuration file or response is well-formed before using it in a project.

Unlike validators that require to paste data into a third-party service, Softaken’s tool performs all checks locally with JavaScript. Softaken’s servers do not transfer or store any JSON content, so it is safe to examine files that may contain sensitive or private information.

Key features of the JSON Validator include:
• Real-time syntax checking with identification of the exact line or character where an error occurs
• A built-in Format JSON option that reindents minified or messy code into a readable structure
• Fully client-side processing, with no server-side file size restrictions
• No account, signup, or payment details required to use the tool
• Continued operation after the page loads, even without an active internet connection
• Consistent behavior across Windows, macOS, and Linux browsers

"Debugging a JSON syntax error by scanning through a file line by line is a common frustration for developers," said a Softaken product representative. "This tool is meant to shorten that process by pointing directly to where the structure breaks down, rather than leaving people to search for it manually."

The JSON Validator is available now at no cost on the Softaken Online Tools page, alongside the company's existing suite of browser-based conversion and formatting tools.
