Sierra, Numbers & excel spreadsheets crashing

[MythicFrost]

Hi,

My dad is having an issue where he opens an Excel spreadsheet (.xlsx) and Numbers immediately crashes before even showing the document. I used Excel to export an empty spreadsheet and sent it to him to test, but it still crashes.

Uninstalling and re-installing allowed him to open one document, but every document after that causes the same crash.

He's running the latest version of Sierra, and the latest version of Numbers. Naturally, he doesn't want to use Excel. The document opens in iCloud and Google Sheets just fine, but neither will export to a Numbers document.

Any idea what the issue is and if it's possible to fix?

It would help if you listed the model of your dad's Mac. However, with the information you have provided it points to a hardware problem. It could be the RAM, or the HDD. I would suggest running diagnostic utilities on your dad's Mac. You could also test the components on a PC with BurnInTest Standard from Passmark.

I can't imagine it's a hardware issue? The computer runs perfectly otherwise. And the SSD, RAM, etc., are all perfectly healthy. The OS was recently (clean) installed too.

The model is the 2013 27" iMac.

Note: this is just a temporary workaround, but he is able to open the document in Numbers on his phone and then send it to himself as a Numbers document, which then works just fine. However this is tedious...
