Microsoft Excel is a spreadsheet program developed by Microsoft (Windows, macOS, Android and iOS), it is part of the Microsoft Office software suite. Just click on the sheet you want to display. The list of sheets is displayed at the bottom of the page. You can also click on drag and drop zone to load your excel file. You can drag and drop your xls or xlx file. Your spreadsheets files are not sent to server side, they do not pass through the network.

You can open microsoft excel documents online without installing software. I’m sure Microsoft will fix this bug eventually, but at least there’s a remedy – even if you have to turn off a valuable and highly touted feature of Windows 10.This tool allows you to open XLS and XLSX files online. Locate the Hey Cortana setting and turn it OFF. To fix the issue and speed up the opening of Excel files, you have to turn off the “Hey, Cortana” feature. Those that never turned on “Hey, Cortana” (which is an awesome feature, btw) have never experienced this problem, hence why the issue exists for some and not others. This issue only exists for Excel and none of the other Office applications. I’ve yet to figure out why this is, but if you turn on the “Hey, Cortana” voice command feature after installing or upgrading to Windows 10, it bogs down Excel file execution.

Why would the experience differ between Windows 10 users? And, that seems to eliminate an Excel issue and put the blame squarely on Windows 10, or at least a component of Windows 10. To further confound the wise, the issue doesn’t exist for everyone. So, it would seem that it’s an Excel issue, right? To make matters more confusing, if you open Excel first (which opens quickly on its own) and then open the file, the file opens blazingly fast. It doesn’t matter if the file is sitting in the Cloud, on a network share, or even locally – it just takes forever to load, even if the file contains no data.

Running either Office 2013 or the latest Office 2016, when opening an Excel file from the file system, it takes close to 20 seconds for the file to open completely. I chalk it up to an errant bug Microsoft missed. The solution is a simple one, but makes absolutely no sense. Last night I had had enough and spent a good hour developing a solution. This is one of the issues that has plagued me since upgrading my systems to Windows 10, but due to a busy travel schedule and other miscellaneous work items, I just delayed digging in to figure out a solution.
