Surprising to see that here. It's usually not the solution that corporations choose and for home use it's good enough. Yeah it doesn't work nearly as well as real Excel but it's manageable for simple things.
My condolences. ServiceNow is straight from hell. It's ridiculously overcomplicated and the layout makes no sense and changes by the time you get used to its shittyness.
It will take literal months to get basic functionality implemented and it will never be pleasant to work with.
Could be much worse. Do kids these days still trick each other into seeing tubgirl or goatse?
