Barcode & QR Parser (Readable Scan String Viewer)
Paste scanner output to split it into readable parts and copy it in a clean format.
GS1 data is parsed into AIs where possible, and unrecognized input is still shown in a usable format.
How to use
- Paste the scanner output into the input field.
- Choose plain or GS1 mode when needed.
- Review the result as a table, JSON, or text, then copy the format you need.

FAQ
Which standards are supported?
The tool works with common barcode and QR scan result strings, splitting and formatting what it can identify. For GS1, it focuses on AI-based best-effort parsing.
What happens if the tool cannot parse the input?
Even when GS1 parsing is uncertain or fails, the tool still shows the original input in a copy-friendly format.
Is my data sent anywhere?
No. Input is processed locally in your browser and is not sent to any external server.
Why do I see symbols like ␝?
Those symbols visualize separators or control characters produced by scanners. You can switch between readable copy and raw-data copy.
Glossary
GS1
A family of identification rules used in retail, logistics, healthcare, and more. This tool parses a practical subset of AIs on a best-effort basis.
AI
Application Identifier. Codes such as 01, 17, and 10 describe the meaning of the following value.
GS
Group Separator. It is a control character used to separate variable-length fields, and this tool shows it as GS(␝).
AIM Symbology Identifier
A prefix such as ]C1 that some scanners add to indicate which symbology was scanned.
Notes
- Industry-specific or company-specific formats may not be fully supported. Always confirm the final interpretation against your own rules or specifications.
- GS1 contains many variable-length fields, so missing separators can make parsing ambiguous. Keep the raw value visible when needed.
- If history saving is enabled, the original input string is stored in this browser's localStorage. Be careful on shared devices.
