How do I overcome the alignment shift problem when quoting for Microsoft Excel?

Question

I have a project to create a repository of output information for an economic analysis for an Excel spreadsheet that I originally created in German. I use the website https://stundenlohnrechner.net/ to create a table of salaries for occupations that play an important role in employment in Germany and place the results of the calculations in rows and columns. However, when I copy the output values from the website, I have to use the font used by the website, which is 19.5 point Arial, when I would like to create the table in Times New Roman and 13 or 14 point font. I can easily change the font size in Excel, but if I want to change the font size at the same time, the entire table is rounded. When copying from a website, how can I make an automatic setting so that a text is automatically copied with the default values I have prepared before? As I usually work with financial tables, I need to copy and insert numbers into tables. And I have this problem very often, especially with decimal numbers showing prices or salaries. I am sure there is a very simple and automatic solution, I am waiting for your solution suggestions: The licensed Excel program I use is usually fine when I quote from German and English websites, but this problem often occurs when I quote from German. I'm wondering if setting English as the default in the language settings will have any impact on resolving this issue.
