# Raising Issues
Issues should generally be accompanied by test files. Since github does not
support attachments, the best method is to send files to <sheetjs@gmail.com>
(subject line should contain issue number or message) or to share using some
storage service. Unless expressly permitted, any attachments will not be
shared or included in a test suite (although I will ask :)
If sending email to a gmail account is problematic, the <dev@sheetjs.com> email
inbox is self-hosted.

## Working with the Workbook
This example walks through every cell of every sheet and dumps the values:
The full object format is described later in this README.
This example extracts the value stored in cell A1 from the first worksheet:
```
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.v;

```
var sheet_name_list = workbook.SheetNames;
sheet_name_list.forEach(function(y) {
sheet_name_list.forEach(function(y) { /* iterate through sheets */
var worksheet = workbook.Sheets[y];
for (z in worksheet) {

* `keys` array (paths in the ZIP) for ZIP-based formats
* `files` hash (mapping paths to objects representing the files) for ZIP
* `cfb` object for formats using CFB containers
- `sheetRows-1` rows will be generated when looking at the JSON object output
(since the header row is counted as a row when parsing the data)
