## Working with the Workbook

The full object format is described later in this README.

This example extracts the value stored in cell A1 from the first worksheet:

```js
var first_sheet_name = workbook.SheetNames[0];
var address_of_cell = 'A1';

/* Get worksheet */
var worksheet = workbook.Sheets[first_sheet_name];

/* Find desired cell */
var desired_cell = worksheet[address_of_cell];

/* Get the value */
var desired_value = (desired_cell ? desired_cell.v : undefined);
```

### Complete Examples

- <https://github.com/SheetJS/js-xlsx/blob/master/bin/xlsx.njs> node

The node version installs a command line tool `xlsx` which can read spreadsheet
files and output the contents in various formats.  The source is available at
`xlsx.njs` in the bin directory.

Some helper functions in `XLSX.utils` generate different views of the sheets:

- `XLSX.utils.sheet_to_csv` generates CSV
- `XLSX.utils.sheet_to_json` generates an array of objects
- `XLSX.utils.sheet_to_formulae` generates a list of formulae
