Developer and security utilities

Check and transform small pieces of data in the browser without setting up a new project.

Validate before transforming

Paste a sample into the JSON validator to find syntax errors before converting it to CSV. Inspect the resulting columns, especially when the source has nested fields.

Use encoders for the right purpose

Base64 and URL encoding change representation; they do not encrypt or protect a secret. Keep sensitive credentials out of content you intend to share.

Inspect generated output

Use the UUID, hash, password and regex tools for focused tasks. Copy and verify the result in the application that will consume it; a browser tool cannot know all of that application’s constraints.

Before you start

Does Base64 encrypt my data?

No. Anyone can decode Base64 text. Use proper encryption when confidentiality matters.

Does valid JSON mean my API will accept it?

No. JSON validation checks syntax; an API may also require a particular field structure and values.
