DAMOA — Free Online Toolbox

What it does

DAMOA is a free, no-signup toolbox with 92+ online utilities for developers and office work: JSON/CSV/YAML tools, regex tester, timestamp converter, calculators, converters, Excel helpers, and more. What makes it different is speed and convenience: one searchable hub (Ctrl+K), bilingual KR/EN UI, mobile + dark mode support, and many tools process data directly in your browser for better privacy.
