UUID Generator

The UUID tool provides two generation modes.

Version	Description
UUID v4	Random-based identifier
UUID v7	Timestamp-based identifier with random data

Usage

Select the UUID tool.
Click UUID v4 or UUID v7.
Review the generated value.
Copy or download the result.

UUID v4

UUID version 4 uses random data to generate an identifier.

Example of the standard UUID v4 format:

f47ac10b-58cc-4372-a567-0e02b2c3d479

UUID v7

UUID version 7 includes a timestamp component, making it useful for time-ordered identifiers.

Example of the standard UUID v7 format:

0199abcd-1234-7def-8123-456789abcdef

The examples illustrate UUID formats rather than actual generated values.

Implementation

WebZone uses crypto.getRandomValues() to generate random bytes.

UUID v7 additionally incorporates the current timestamp in milliseconds.

Implementation note: The supplied UUID functions contain an extra .slice(1) after formatting the identifier string. This appears to remove the first hexadecimal character from the generated UUID. Until corrected, generated identifiers should be checked for the standard 36-character UUID format before use.

Color Conversion

The Color Converter translates values between HEX, RGB, and HSL representations.

Supported Formats

Format	Example
HEX	`#1f2937`
RGB	`rgb(31, 41, 55)`
HSL	`hsl(215 24% 17%)`

The sample HSL value is an approximate equivalent of the HEX and RGB examples.

Usage

Select Color.
Enter a color value in one of the fields.
Click the corresponding conversion button.
Review the converted values and preview swatch.

HEX Input

WebZone supports three-digit and six-digit HEX values.

Examples:

#fff
#ffffff
#1f2937

The leading # is optional for HEX parsing.

RGB Input

RGB input follows the format:

rgb(255, 100, 50)

Each component conventionally ranges from 0 to 255.

HSL Input

HSL input supports forms such as:

hsl(215 24% 17%)

or:

hsl(215, 24%, 17%)

Hue is conventionally expressed in degrees, while saturation and lightness are percentages.

Color Preview

The converter updates a visual swatch using the converted HEX color.

Limitations

The tool does not provide alpha-channel conversion through RGBA or HSLA.

RGB and HSL inputs are matched using numeric patterns; those checks do not fully enforce conventional component ranges.

Some conversions involve rounding.

Text Statistics

The Text Statistics tool analyzes plain text and produces several measurements.

Usage

Select Text Statistics.
Enter or paste text.
Click Analyze.
Review the statistics.

Available Measurements

Statistic	Description
Characters with spaces	Total JavaScript string length
Characters without spaces	Length after removing whitespace
Words	Number of whitespace-separated segments
Lines	Number of lines
Sentences	Number of punctuation-terminated text segments
Paragraphs	Number of nonempty sections separated by blank lines

Example

Input:

Hello, world!
Welcome to WebZone.

Expected results:

Statistic	Result
Characters with spaces	33
Characters without spaces	29
Words	5
Lines	2
Sentences	2
Paragraphs	1

Counting Behavior

Characters

The implementation uses JavaScript string length.

Some Unicode characters are represented by multiple UTF-16 code units and may therefore count as more than one character.

Words

Words are identified through non-whitespace segments, not full linguistic analysis.

Sentences

Sentences are approximated using punctuation including periods, exclamation marks, and question marks.

A final sentence without terminating punctuation may not be counted.

Paragraphs

Paragraphs are separated by blank lines.

Common Uses
