# excel2df 

A library for converting Excel files to Polars DataFrame

**excel2df** is a pure Rust library to read excel files(.xlsx) in to Polars DataFrame.

Now it supports multi_threads to read excel files. It can save more time.

# Examples


## Sigle thread to read excel file

```rust
use excel2df::Workbook;

let wb = Workbook::open("./test.xlsx").unwrap();
let range = wb.get_sheet_range("Sheet1");
let df = range.to_dataframe(0);
println!("{:?}", df);
```

## Multi thread to read excel file

```rust
fn main(){
    let mut wb = Workbook::new("./sale.xlsx").unwrap();
    wb.set_threads_num(6);//set threads num

    let start = Instant::now(); 
    let range = wb.get_sheet_range2("Sheet1");
    let df = range.to_dataframe(10);

    let duration = start.elapsed();
    println!("Runing time: {:?}", duration);
    println!("Runing: {} miliSeconds", duration.as_millis());
    println!("{:?}",df)
}
```
