Quick Tool Overview

Insert Text adds text at a character position, at a fixed interval, or before and after every match of a word. The interval mode is what formats card numbers, MAC addresses and licence keys; the wrap mode tags every instance of a term through a document.

About the Insert Text

Inserting text at a regular interval is the job behind a surprising number of small tasks: putting a space every four digits of a card number, a colon every two characters of a MAC address, a hyphen every five characters of a licence key, or a line break every eighty characters of a long string.

This inserts at whatever point you specify. By character position for a single insertion, at a fixed interval for formatting, or before and after every occurrence of a word — which is how you wrap a term in asterisks throughout a document, or tag every instance of a name. Insertion runs line by line or across the whole text, and the count of insertions made is reported so you can confirm it hit what you expected.

Key features of the Insert Text

Fixed-interval insertion

A space every four digits, a colon every two characters — the formatting rules that come up constantly.

Wrap every match

Different text before and after each occurrence of a word, for bolding or tagging a term throughout.

Ignore existing whitespace

Count only the real characters, so a partly formatted value reformats consistently.

Per-line or whole-text

Apply the rule to each row independently, or to the document as one continuous string.

Insertion count reported

How many insertions were made, so you can confirm the rule matched what you intended.

Frequently asked questions

Insert a space at an interval of four characters. A sixteen-digit number becomes four groups of four, which is how card numbers are printed and how most forms expect them.
