When I have an excel file with some cells formatted with currency, the conversion does not include the currency label. It only seems to extract the value.

For example an excel file with the following:

Returns:
'## Sheet1\n| Unnamed: 0 | Unnamed: 1 | Unnamed: 2 | Unnamed: 3 | Unnamed: 4 |\n| --- | --- | --- | --- | --- |\n| Item | Count | Cost | Weight | Total |\n| Breakfast | 20 | 5 | NaN | 100 |\n| Laptops | 5 | 1199 | NaN | 5995 |\n| Car tires | 8 | 199 | 150 kg | 1592 |\n| NaN | NaN | NaN | NaN | 7687 |'
