## What this tool does
Convert any exchange transaction CSV (Binance, Coinbase, Kraken…) into Koinly import format with automatic column mapping.

## Typical user problems
- Every exchange exports trades in its own column names, and Koinly needs one exact template — reshaping thousands of rows by hand before tax season is misery.

## Parameters
- fiat_currency: enum, required. 法币计价

## Pricing
- Watermarked preview: free, no login required
- Final clean output: $0.99 one-time per task
- Require login (email/phone OTP) to complete payment
- Result available for download 24 hours after payment

## Limitations
- Max input 20 MB
- trade/swap 行若带 From/To 列则映射双边，否则按买入单边处理
- 金额数字须为点号小数（欧洲 1.234,56 格式可识别，但 1,23 逗号小数可能歧义）
