Make repetitive changes to lines of text.
Paste your text here, then apply edits.
Changes will update-in-place.

Example use case:
You have a list of plain GUIDs and you want to format them to be used in a SQL where clause like this "where Column in ('GUID', 'GUID', 'GUID'..."

1) Paste the GUID list into the text area
2) Use "Add Prefix" to add a ' at the start of each line
3) Use "Add Suffix" to add a ', at the end of each line
Done
