# **UUID Validator**

Validate UUIDs and detect their versions

**UUID (one per line)**

Validate multiple UUIDs by separating with line breaks.

## **Validation Results**

## What is UUID Validator?

UUID Validator is a tool for validating multiple UUIDs at once and checking their versions. Enter one UUID per line to review the results in a table and export them as CSV.

It is useful for data review, API testing, log inspection, and other workflows that handle UUID values in bulk.

## How to Use

1. Enter one UUID per line.
2. Review validity and version in the result table.
3. Sort the result table by validity or version when you want to compare entries side by side.

## Use Cases

- Reviewing UUIDs in database exports or CSV data
- Checking UUID fields in API requests or responses
- Inspecting UUIDs in logs or migration data

## Things to Keep in Mind

- Blank lines and trailing blank lines are ignored.
