## 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

**Required fields:** `text` - the Base64-encoded string
**Example:**
```json
{
"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:**
```json
{
"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:**
```json
{
"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:**
```json
{
"action": "encode-html-entity-encode",
"text": "<div class=\"main\">Hello & welcome</div>"
}
```
Returns `<div class="main">Hello & welcome</div>`.
---
##### encode-html-entity-decode
Convert HTML entities back to their original characters.
**Required fields:** `text` - the HTML-entity-encoded string
**Example:**
```json
{
"action": "encode-html-entity-decode",
"text": "<p>Hello & welcome</p>"
}
```
---
##### 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:**
```json
{
"action": "encode-escape-json",
"text": "Line 1\nLine 2\tTabbed \"quoted\""
}
```
Returns `Line 1\\nLine 2\\tTabbed \\\"quoted\\\"`.
---
##### encode-unescape-json

```json
{
"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:**
```json
{
"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:**
```json
{
"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:**
```json
{
"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:**
```json
{
"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:**
```json
{
"action": "encode-rot13-encode",
"text": "Hello World"
}
```
Returns `Uryyb Jbeyq`. Applying ROT13 again to the result returns the original text.
---

Convert Unicode characters to their escape sequences (e.g., `\uXXXX`).
**Required fields:** `text` - the text containing Unicode characters
**Example:**
```json
{
"action": "encode-unicode-escape",
"text": "Caf\u00e9 \u2603"
}
```
---
##### encode-unicode-unescape

**Required fields:** `text` - the string containing `\uXXXX` escape sequences
**Example:**
```json
{
"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.
