UUID Generator – Generate UUID v4 in Bulk

This UUID Generator tool creates one or multiple UUIDs using UUID version 4 (random) and displays them instantly in a clean output area. You can choose how many UUIDs you want to generate (from 1 to 1000) and then copy the full result with a single click.

The tool is built with a Django backend endpoint that generates UUIDs and a frontend interface that displays output, tracks counts, and provides copy/clear actions.

What Is a UUID?

A UUID is a Universally Unique Identifier — a standardized identifier commonly represented as a 36-character string (including hyphens). This tool generates UUIDs in the standard text format and outputs them as a list.

UUID Version Used by This Tool

This tool always generates UUID v4, meaning:

• UUIDs are generated randomly

• Every generated item is created using uuid.uuid4() on the backend

(Your code does not provide other UUID versions.)

Key Features

1) Bulk UUID Generation (1–1000)

• User selects a count

• Backend generates exactly that many UUID v4 values

• Output is returned as newline-separated text

2) Output as One UUID Per Line

• The backend joins UUIDs using \n

• The UI displays the output in a <pre> block for readable formatting

3) Copy UUIDs Button

• Copy button stays hidden until UUIDs are generated

• After generation, copy becomes visible and enabled

• Copy uses navigator.clipboard.writeText() with a fallback method for older browsers

4) Clear All

• Clears output

• Hides the copy button again

• Resets counts (UUID count + character count)

5) Live Counts

The UI shows:

• UUIDs generated (computed by counting non-empty lines)

• Character count (length of output text)

6) Loading State

While generating:

• Generate button becomes disabled

• Button text changes to “Generating…” with a spinner icon

7) Count Validation

Frontend and backend both enforce:

• Minimum 1

• Maximum 1000
  If out of range, the tool shows an error (toast) and blocks generation.

8) Error Toast Notifications

If:

• invalid count

• network issue

• backend error
  …the tool shows a red toast message at the top-right.

9) UI Theme Support

Your CSS includes:

• dark theme default

• .light-theme overrides for light mode

10) Responsive Layout

On smaller screens:

• settings panel and buttons stack vertically

• output area height adjusts

How This Tool Works

1. User enters a number in “Number of UUIDs to generate”

2. User clicks Generate UUIDs

3. Frontend sends a POST request to /tools/uuid-generator/convert/ with { count }

4. Backend validates count (must be 1–1000)

5. Backend generates UUID v4 values and returns them joined by newlines

6. Frontend displays the result and updates:

   • UUID count

   • character count

7. User can Copy or Clear All

Input Rules & Limits

• Count must be a number between 1 and 1000

• If the value is empty/invalid, the input is auto-corrected to fit the allowed range

Output Format

• Plain text output

• One UUID per line

• Displayed in a scrollable output container

• Auto-scrolls to bottom if output becomes large

Copy & Clear Options

• Copy UUIDs copies the full output exactly as displayed

• Clear All resets the tool state and hides the copy option

Error Handling

The tool can show errors for:

• invalid count range

• backend failure response

• network issues

• attempting to copy when output is empty

Conclusion

This UUID Generator produces UUID v4 values in bulk (up to 1000), displays them in a clean list format, and provides quick actions to copy or reset results, with input validation and user-friendly feedback built in.
