NOTE: Under 'Variable View' make sure your variables numbers are set to Numeric (under type) and to Scale (under Measure). To be safe, I usually copy and paste an identical column right next to the original column so that I have another copy incase the data gets deleted when I switch the variable type from String to Numeric. The reason you should do this so you can change your variable type from String to Numeric without deleting any of the data. Once you finish in Excel and ALL the words are turned into numbers THEN import the excel sheet to SPSS. Alternatively, you can replace the words manually without the replace function, but this takes more time. I have made the mistake of using the same number to replace two different words.
To assign numbers to words you simply type the word in you want to replace (e.g., Zilnic) and then enter the number you want to replace it with (1 or 5, I don't know Romanian lol).
It is my experience that using Excel to clean your data is much more user friendly than SPSS. SPSS handles the inclusion of mismatched records in a one to-many merge differently than a one-to-one merge. So now what you have to do is clean your data. That way when you import that data the responses will be numbers and not the words that represent the numbers. Then for the given responses use the numbers 1 to 5 rather than the words (e.g., Zilnic). For example, when you ask how often one uses a specific social media platform, it's best to say "Respond on the given scale from 1 (not at all) to 5 (always)". In the future know that the way you set up your online survey will influence what your data looks like when you export it from whatever platform you are using. This assignment allows you to become familiar with importing Microsoft® Excel® (or some other type of data) into SPSS and using the Analysis tab (for frequencies).
