#Random Code Maker Introduction# It is a free browser-based tool for generating unique codes in bulk — voucher codes, passwords, serial numbers, API keys, ticket references, employee IDs and more. Set a pattern, pick a quantity, export to CSV or Excel. Done in seconds.
Every code is generated directly in your browser. Nothing is sent to a server, nothing is logged, no account required.
The pattern system is simple but powerful. Tokens like X (uppercase), 9 (digit) and # (any character) let you define exactly the format you need — add a prefix, exclude ambiguous characters, and guarantee uniqueness across the whole batch. A sequential generator handles ordered series like invoice numbers using an auto-incrementing {n} token.
Key features:
- Generate up to 2,000 codes per batch, export as TXT, CSV, JSON or Excel
- 36 specialist generators — passwords, API keys, vouchers, gift cards, serial numbers, UUIDs, OTPs and more
- QR code and barcode generators with bulk ZIP download
- Saved patterns, import/export settings, entropy-based strength meter
- 20 languages including Arabic (RTL), Chinese, Hindi, Korean and Thai
It's flexible enough for developers who want precise control, and simple enough for anyone who just needs something that works — no scripts, no spreadsheet formulas, no signup.
