About JSON & String Lab
JSON & String Lab is a collection of practical browser-based tools for formatting JSON, cleaning text, converting strings, building SQL lists, encoding URLs, decoding Base64, testing regular expressions, and working with common developer data formats.
The goal is simple: give users a fast workspace for small text transformations without requiring an account, upload workflow, or server-side processing for normal tool usage. The tools are designed for developers, analysts, students, testers, writers, and anyone who needs quick formatting or cleanup while working in a browser.
Many tools run entirely on the client side. That means pasted content is transformed in your browser for the core workflow. Users should still avoid pasting passwords, production secrets, private customer records, or regulated data into any website unless their organization explicitly approves that use.
