#### Excel

After importing the tablesaw-Excel dependency, you can use the following to read all the sheets in excel.

```Java
XlsxReadOptions options = XlsxReadOptions.builder("<excelFileName>.xlsx").build();
XlsxReader xlsxReader = new XlsxReader();
List<Table> tables= xlsxReader.readMultiple(options);
```

Paricular sheet can be read using `.sheetIndex(int <index>)`:

```Java
XlsxReadOptions options = XlsxReadOptions.builder("<excelFileName>.xlsx").sheetIndex(1).build();
XlsxReader xlsxReader = new XlsxReader();
List<Table> tables= xlsxReader.readMultiple(options);
```
