• Use our free CLI tool (unlimited size)
• Purchase a one-off browser credit ($5 for 24h)

✨ Features

• Smart auto-mapping - Fuzzy matches your CSV headers to target schema fields
• Validation - Shows specific errors and suggests fixes
• No signup required - Start mapping immediately
• Privacy-safe - Files never leave your device (browser-only processing)
• Open source - MIT licensed, contribute on GitHub
• CLI included - Unlimited file size, perfect for automation
