String Inspector
When you need to process source code or structured data with the controls provided, String Inspector gives you a browser-based workflow with a visible input, primary action, and the resulting output.
How to Use String Inspector
- Prepare source code or structured data and enter or select source code or structured data in the workspace.
- Review the available options, then choose Inspect String to run the task.
- Inspect the resulting output, compare it with the source and selected settings, and save or copy it only after it meets your requirements.
What Is the String Inspector?
The String Inspector is a free online utility that helps you inspect string length, characters, whitespace, and encoded details. It provides a focused workspace for developers, QA teams, designers, students, and technical writers.
Use this inspector while debugging, validating assumptions, or comparing input against expected application behavior. The current interface gives you Input, Result so the task can be completed without navigating away from the page.

When to Use This Tool
- Quick one-off tasks using the String Inspector without setting up a separate desktop utility.
- Checking or preparing data while debugging, documenting, publishing, or testing a workflow.
- Creating a clean result that can be copied, downloaded, or transferred into another application.
Tips for better results
- Test both a known-good example and an intentionally invalid example.
- Do not rely on one browser-side check as a substitute for server-side validation.
- Save representative test cases when the same format or pattern is used repeatedly.
String Inspector Example
Paste a minimal valid sample into source code or structured data, run String Inspector, and test the the resulting output in the target application before using it with a larger production payload.
Frequently Asked Questions
Which input works best in String Inspector?
