### What is the difference?

[12]: src/converters.ts#L13
[13]: src/converters.ts#L30

* **converter 1** or **converter 2**? The difference is in the algorithm of convertation. You can compare [the first method][12] with [the second method][13].
* **".min"?** Minified version.
* **Default version** in npm is ESM. This version is not transpiled and minified, so you need to transpile and minify it.

## Initialization
```js
import A1 from '@flighter/a1-notation';
```

## API

**Note:** A1 string could be represented in any register. `A1 === a1`, `A1:B2 === a1:b2 === A1:b2 === a1:B2`
