Using NFP (Number Format Parser) you can get an Abstract Syntax Tree (AST) from Excel number format expression.

## Installation

```bash
go get github.com/xuri/nfp
```

## Example

```go
package main

import "github.com/xuri/nfp"

func main() {
    ps := nfp.NumberFormatParser()
    tokens := ps.Parse("_(* #,##0.00_);_(* (#,##0.00);_(* \"-\"??_);_(@_)")
    println(p.PrettyPrint())
}
```
