I am starting to play with pandas.

I downloaded a google sheet.

When reading some data from excel in win7:

```
xls = pd.ExcelFile('C:/Users/file.xlsx')
data = xls.parse('Sheet 1', index_col=None, na_values=['NA'])
print "Data", data 

```

I am a getting:

```
Decode error - output not utf-8

```

The original excel file has text and numbers.

What is wrong?

Thanks,
