What This Tool Does

A text transformation utility that converts strings between various encoding formats commonly used in web development, data transmission, and programming. It provides bidirectional base64 encoding and decoding for binary-to-text representation used in data URLs, API payloads, and email attachments. URL encoding applies percent-encoding for safe transmission of special characters in query strings and path segments, while URL decoding reverses the process for parsing incoming requests. HTML entity encoding escapes special characters like angle brackets, ampersands, and quotes for safe inclusion in HTML documents, preventing XSS vulnerabilities and rendering issues. JSON string escaping handles special characters including newlines, tabs, backslashes, and quotes for embedding text within JSON structures. Hexadecimal conversion transforms text to and from hex representation for debugging, cryptographic applications, and low-level data inspection. Binary encoding produces space-separated 8-bit representations for educational purposes and bit-level analysis. ROT13 applies the classic letter substitution cipher that shifts characters by 13 positions, useful for simple text obfuscation. Unicode escape sequences convert non-ASCII characters to backslash-u notation for source code compatibility and cross-platform text handling. All operations include metadata about input and output lengths.

Product Instructions

Data Format Encoder

Encode, decode, escape, and convert text between multiple data formats including Base64, URL encoding, HTML entities, JSON, hexadecimal, binary, ROT13, and Unicode.

Actions

encode-base64-encode

Encode plain text to Base64 format.

Required fields: text - the plain text to encode

Example:

{
  "action": "encode-base64-encode",
  "text": "Hello world!"
}

Returns the Base64-encoded string (e.g., SGVsbG8gd29ybGQh).

encode-base64-decode

Decode a Base64-encoded string back to plain text.

Required fields: text - the Base64-encoded string

Example:

{
  "action": "encode-base64-decode",
  "text": "SGVsbG8gd29ybGQh"
}
encode-url-encode

Percent-encode text for safe use in URLs.

Required fields: text - the text to URL-encode

Example:

{
  "action": "encode-url-encode",
  "text": "hello world & goodbye"
}

Returns hello%20world%20%26%20goodbye.

encode-url-decode

Decode a percent-encoded (URL-encoded) string back to plain text.

Required fields: text - the URL-encoded string

Example:

{
  "action": "encode-url-decode",
  "text": "hello%20world%20%26%20goodbye"
}
encode-html-entity-encode

Escape special HTML characters (e.g., <, >, &, ") into HTML entities.

Required fields: text - the text containing HTML characters

Example:

{
  "action": "encode-html-entity-encode",
  "text": "<div class=\"main\">Hello & welcome</div>"
}

Returns &lt;div class=&quot;main&quot;&gt;Hello &amp; welcome&lt;/div&gt;.

encode-html-entity-decode

Convert HTML entities back to their original characters.

Required fields: text - the HTML-entity-encoded string

Example:

{
  "action": "encode-html-entity-decode",
  "text": "&lt;p&gt;Hello &amp; welcome&lt;/p&gt;"
}
encode-escape-json

Escape special characters in text for safe embedding inside JSON strings (e.g., newlines, tabs, quotes).

Required fields: text - the text to JSON-escape

Example:

{
  "action": "encode-escape-json",
  "text": "Line 1\nLine 2\tTabbed \"quoted\""
}

Returns Line 1\\nLine 2\\tTabbed \\\"quoted\\\".

encode-unescape-json

Convert JSON-escaped sequences back to their original characters.

Required fields: text - the JSON-escaped string

Example:

{
  "action": "encode-unescape-json",
  "text": "Line 1\\nLine 2\\tTabbed \\\"quoted\\\""
}
encode-text-to-hex

Convert text to its hexadecimal byte representation.

Required fields: text - the plain text to convert

Example:

{
  "action": "encode-text-to-hex",
  "text": "Hello"
}

Returns 48656c6c6f.

encode-hex-to-text

Convert a hexadecimal string back to plain text. Spaces, colons, and hyphens between hex bytes are automatically removed.

Required fields: text - the hexadecimal string

Example:

{
  "action": "encode-hex-to-text",
  "text": "48 65 6c 6c 6f"
}
encode-text-to-binary

Convert text to its 8-bit binary representation (space-separated bytes).

Required fields: text - the plain text to convert

Example:

{
  "action": "encode-text-to-binary",
  "text": "Hi"
}

Returns 01001000 01101001.

encode-binary-to-text

Convert an 8-bit binary string back to plain text. The binary string length must be a multiple of 8 bits.

Required fields: text - the binary string (spaces between bytes are optional)

Example:

{
  "action": "encode-binary-to-text",
  "text": "01001000 01101001"
}
encode-rot13-encode

Apply the ROT13 substitution cipher to text. ROT13 is its own inverse -- apply it again to decode.

Required fields: text - the text to encode/decode

Example:

{
  "action": "encode-rot13-encode",
  "text": "Hello World"
}

Returns Uryyb Jbeyq. Applying ROT13 again to the result returns the original text.

encode-unicode-escape

Convert Unicode characters to their escape sequences (e.g., \uXXXX).

Required fields: text - the text containing Unicode characters

Example:

{
  "action": "encode-unicode-escape",
  "text": "Caf\u00e9 \u2603"
}
encode-unicode-unescape

Convert Unicode escape sequences back to their original characters.

Required fields: text - the string containing \uXXXX escape sequences

Example:

{
  "action": "encode-unicode-unescape",
  "text": "Caf\\u00e9 \\u2603"
}

Common Workflows

  • Prepare text for a URL query parameter: Use encode-url-encode to safely encode user input before appending it to a URL.
  • Embed user content in HTML: Use encode-html-entity-encode to prevent XSS or rendering issues when inserting text into HTML.
  • Store or transmit binary data as text: Use encode-base64-encode to convert binary content to a text-safe format, and encode-base64-decode to restore it.
  • Inspect raw byte values: Use encode-text-to-hex or encode-text-to-binary to see the byte-level representation of any string.
  • Simple text obfuscation: Use encode-rot13-encode to lightly obscure text (e.g., hiding spoilers). Apply it twice to get the original back.

Important Notes

  • All actions require the text field except get_instructions.
  • Decoding actions will return an error if the input is not valid for the expected format (e.g., invalid Base64, non-hex characters, binary string not a multiple of 8 bits).
  • Hex decoding automatically strips spaces, colons, and hyphens, so formats like 48:65:6c:6c:6f or 48-65-6c-6c-6f are accepted.
  • ROT13 only rotates ASCII letters; digits, punctuation, and non-ASCII characters pass through unchanged.
  • All text processing uses UTF-8 encoding.
