Add a Prefix or Postfix

Prepare one shared affix and choose which end of each row receives it.

Prefix or Suffix Lines

1. Paste the source rows into Insert list. Enter the text to add in Enter prefix or postfix.
2. Leave Postfix cleared to prepend the text. Select Postfix to append the text after each row instead.
3. Click Add to process the current input.
4. Read Result and Number of rows. The tool joins the added text directly to each row without inserting an automatic separator.
5. Click Copy under the output you want to keep. Use Clear where shown to clear the text fields; option selections stay as set.

For 123 and 456, enter ID- and leave Postfix off. Result is ID-123 and ID-456.

Outer whitespace in the affix is trimmed

Leading and trailing whitespace in Enter prefix or postfix is removed before addition. A trailing space in a proposed prefix is not preserved, so use a visible separator such as a hyphen when appropriate.

Choose one end at a time

The form supplies one affix field and a Postfix switch. To add different text at both ends, copy the first result back into the source and run a second operation with the other direction.

Append a postfix instead

Select Postfix, enter the desired suffix in Enter prefix or postfix, and click Add. For example, suffix -done changes 123 to 123-done.
