Quick Start: Generate Random Numbers
Open HeronTool's Random Number (随机数生成), simply set the range (e.g., 1-100) and quantity, then click generate. Ideal for lottery numbers or test data. To shuffle an existing list, use Shuffle Lines (行乱序), paste your text lines, click shuffle, and copy the result.

FAQ
Q: Can generated random numbers repeat? By default, duplicates are not allowed unless you specify otherwise; you can adjust the setting.
Q: How strong is the password generator? It uses a cryptographically secure random source, but we recommend at least 12 characters with mixed types.
