Best for: API examples, software configurations and structured data.

JSON is often used by apps and websites to exchange information. When an API response is compressed into a single line, nested data can be hard to read. The JSON Formatter & Validator makes valid JSON easier to inspect by adding indentation. Its validation step also alerts you when the input cannot be parsed as strict JSON.

{"product":"notebook","price":25,"inStock":true}

If you add a trailing comma before the final closing brace, the text becomes invalid JSON. The formatter will report a parsing error rather than silently inventing a correction. Learn more in our guide to 12 common JSON errors or see why AI-generated JSON sometimes fails validation.

Best for: blog drafts, product descriptions, assignments and short copy.

When preparing a blog post or social caption, you may need to check the length rather than rely on an AI assistant's approximation. The Word & Character Counter updates as you type and shows word count, character count, sentence count and estimated reading time.

Small tools make everyday work easier.

A higher word count does not automatically mean a better article. Review relevance, accuracy and structure before publishing. For a more complete editing workflow, read how to measure AI-generated content before publication.

Best for: preparing headings, organizing text and cleaning up copied content.

Copied text can arrive in inconsistent capitalization, especially when it comes from spreadsheets, imported documents or design drafts. The Text Case Converter lets you change text without retyping every word.

Automatic title case is a quick formatting aid, not an editorial style checker. Brand capitalization, names and style rules may still need a human review.

Best for: campaign names, query values and links containing spaces or special characters.

Marketing links and application URLs often contain values with spaces, punctuation and ampersands. These characters can be misunderstood when they're inserted directly into a URL query. The URL Encoder & Decoder helps convert an individual text value into a percent-encoded representation.

Important: this utility uses component encoding. Do not paste a complete website address, encode all its separators and assume the result is a normal clickable link. For proper marketing tracking, see how to encode URL parameters for campaigns.

Best for: showing code snippets as text and understanding basic HTML escaping.

Characters such as <, > and & have special meaning in HTML. If you want to show an HTML example in a page rather than have the browser interpret it as markup, you may need to encode those characters. Our HTML Entity Encoder helps demonstrate this transformation.

<h2>Tips & tricks</h2>

Encoding a sample string is not a complete defense against cross-site scripting or unsafe input. Real applications must escape according to the output context and follow secure coding practices.

Best for: educational examples, data formats and debugging encoded text.

Base64 represents bytes using a limited set of printable characters, making it useful in some email formats, APIs and data URLs. It is easy to reverse, so it should never be treated as encryption. The Base64 Encoder & Decoder lets you try a reversible transformation with sample text.

Hello

If you work with APIs, check the required text encoding and whether the service expects standard Base64 or Base64URL. Our detailed Base64 developer guide covers both variants and common mistakes.

Best for: CSS edits, brand palettes and checking color value formats.

Website colors may be written as HEX, RGB or HSL values. These formats can represent the same sRGB color in different notations. If you're working with an existing brand color, a quick conversion can save calculation time when updating stylesheets.

Converting values does not guarantee readable text contrast. When designing buttons and content, evaluate the actual foreground/background pair. Learn more from the HEX vs RGB vs HSL website design guide.

Best for: basic public-network checks and learning about IP metadata.

An IP address lookup can return approximate network information for a public IP address. Our IP Address Lookup provides a simple interface for such checks. Unlike the text transformation tools above, it makes a request to an external lookup provider, so the provider receives data needed to perform the query.

Privacy distinction: the IP lookup uses the third-party service ipapi.co. If you leave the input empty, the provider may use the requesting device's public IP. Do not assume an approximate IP location identifies a person's precise location, and avoid using IP metadata as proof of identity.
