如何在Notepad++中移除CSV单元格内的CR换行符，实现单行记录

Got it, let's get this CSV sorted out—your issue is perfect for Notepad++'s advanced find-and-replace tools. Here's exactly what to do:

• First, open your CSV in Notepad++. To make sure you're targeting the right characters, turn on "Show All Characters" via View > Show Symbols > Show All Characters. This will let you see the CR (\r) markers inside cells and the LF (\n) markers at the end of each record.
• Open the Replace dialog by pressing Ctrl+H (or go to Edit > Replace).
• In the Find what field, enter \r—this is the escape sequence for the CR character you want to remove.
• Leave the Replace with field empty (or if you'd prefer to replace the line break with a space for readability, type a single space here).
• Crucially, switch the Search Mode to Extended (\n, \r, \t, \0, \x...)—this tells Notepad++ to recognize the escape characters instead of treating \r as literal text.
• Click Replace All, and that's it! All the CR markers inside your cells will be removed, leaving each full CSV record as a single line ending with LF.

This works because we're only targeting the standalone CR characters (the ones inside cells) while leaving the LF characters (which mark the end of each record) untouched.
