How do I make my dataset such that all items called "Shoe and boxes" are labeled "Shoes and boxes" instead?
In other words such that the first table becomes the second table?
I have tried several if formulas, but without luck. I am a real newbie, and appreciate your kind help! 
| Item | Price |
| Trouser | 100 |
| Shoes and boxes | 30 |
| shoe and boxes | 10 |
| Jeans | 100 |
| Top | 90 |
| Shoe and boxes | 30 |
