How is understanding newline characters history helpful today?

Well I recently had to help a friend who was having trouble copy-pasting part of an Excel spreadsheet into a Word Document.

They were very frustrated by the fact that one of the rows in the document was taking up three lines and adjusting it with the mouse wasn’t allowing it to be smaller.

I didn’t have too much trouble figuring out the problem because I am familiar with core concepts of how there are unprintable newline characters. One of the cells contained some text with at the end had some hidden newline characters which although it didn’t alter the size of the row in Excel, the implementation in Word was not allowing that row to be compressed into one line.

By deleting the newline characters I was able to help my friend get to display the chart in one line.
