So there are a few ways to do this, maybe even more than those listed below. It is instructive to have different means, as the techniques could be useful in similar situations.
Method 1: Put the caret in column 1 of the first line you want to affect (since you said “each row”, this would be line 1). Go to the Edit (menu) and invoke Column Editor… In the Column Editor dialog box that pops up, tick Text to Insert Put your desired text in the zone that appears below Text to Insert Click OK Notepad++ will add your specified text to the beginning of every line.Note: You can make the starting line for this action variable, but I don’t believe you can specify an end-point to this action; it affects all lines from the line of the caret up to and including the last line of the file. Method 2: Make sure you are in “insert” mode rather than “overwrite” mode (check far-right of status bar for “INS” rather than “OVR”) Put the caret in column 1 of the first line you want to affect (since you said “each row”, this would be line 1). Go to the Edit (menu) and invoke Begin/End Select Go to column 1 of the line ABOVE the last line you want to affect (since you said “each row”, this would be the line above the last line in the file). Press and hold Ctrl and Alt while you press-and-release the down-arrow key. You should have a double-height skinny caret in column 1 of the last line of the file and the line above. Go to the Edit (menu) and invoke Begin/End Select You should now have a skinny caret in column 1 of the entire file. Type your desired text which will then appear at the start of every line. Move the caret with an arrow key to return the caret to normal.
Note: This can be made to affect only a desired range of lines in your file (doesn’t have to be ALL lines); determined by where you do the two Begin/End Selects. Method 3: Go to the Edit (menu) and invoke Select All (default keycombo: ctrl+a) Invoke the Replace dialog (Search menu, then Replace…) In the Find-what zone, put ^ In the Replace-with zone, put your desired text In the Search-mode zone, choose Regular expression Tick the In selection checkbox Press the Replace All button.
Note: This can be made to affect only a desired range of lines in your file (doesn’t have to be ALL lines); determined by the range of lines in your selected text.
Note: Apologies to @JimDailey , but I already had Method 3 typed when I saw you had responded–good thing we agree on the basic technique. :-)
