Data Cleaning

I am learning data science and have a project with a messy spreadsheet. Some rows have missing values, while other entries use different formats. I know the data should be cleaned before analysis, but I am not sure which step should come first. I saw the phrase do my eView assignments while searching for study help, but I want to understand the process myself. Should I remove empty rows first or check for duplicate records? What simple steps do beginners usually follow when cleaning a small dataset?
