I have an existing spreadsheet and would like to view and use the filters of it on my iPhone. I can turn it into an XLS if needed, but I have to be able to click the drop-down arrow on the top of the column and filter the sheet. It would be nice if I could edit it but that's not as necessary as just using it. I don't care if it's a free app or I pay for it - I just need the functionality.
Anyone know of an app such as this?
