Base64 to JSON

What is Base64 to JSON?

Base64 to JSON is a browser-based developer utility for decode UTF-8 Base64 text and validate the resulting JSON document. It keeps source data on the device for normal formatting, validation and conversion actions, so code and API payloads are not uploaded simply to process them. The workspace provides syntax-aware editing, keyboard access, file loading, copy and download controls, and clear errors designed for practical debugging rather than a generic failure message.

Decode UTF-8 Base64 text and validate the resulting JSON document.

How to use Base64 to JSON

1. Paste JSON, load the original sample, or choose a local .json or .txt file.
2. Choose the relevant action and review validation details before using the output.
3. Switch between code and tree views when structural inspection is useful.
4. Copy or download the result; enable input memory only when the document is not sensitive.

Features

• Local-first processing with UTF-8 and Unicode support
• CodeMirror editing with search, history and bracket matching
• Accessible validation status with line and column details
• Responsive code and tree views with dark-mode support
