Finally one that works!

Quick Office Pro was my app of choice for Excel but it died through some update at the end of April 2015. Crazy but I’ve been searching and buying a replacement Excel app ever since. I absolutely DON’T want to put my sensitive clients details up to any cloud service just to make my app sync.
All the apps I tried that claimed wifi sync and full Excel compatibility including iSpreadsheet, docs2go, spreadsheet touch,Documents Free, and another with a big “D” for an icon don’t work right! None could actually use an Excel sheet imported into the iphone, seriously regardless of their claims. Most just used a “picture” of the spread sheet so you could’t look into a cell if there was numbers or text that was originally too large. e.g. a long 1-800 tel number couldn’t be shown if the original on the computer didn’t previously have that cell expanded.
Further, some sort of worked if you first converted you Excel files into csv formats.
This app works! Thank you!
