Bulk Add Prefix & Suffix Tutorial: One-Click Line Affixes

2026-09-20 · Card Tools

Wrapping every line of text with a prefix or suffix is one of the most common tasks when processing cards: adding a platform marker to a batch of raw card numbers, stitching loose numbers into full redemption links, or appending an expiry note to each line. Editing hundreds of lines by hand is slow and easy to miss a line — Add Prefix & Suffix does it all at once.

1. Typical use cases

• Normalize the format: batch-add a platform prefix such as VIP- or GD- to exported raw card numbers;
• Build links: turn each number into a full URL, e.g. https://example.com/exchange/ followed by the card number;
• Add notes: append a batch number or expiry date to the end of every line;
• Use both sides at once: a platform name as the prefix and a date as the suffix, done in one pass.

2. How to use it

1. Type the text to prepend into Prefix (start of each line); it can be left blank;
2. Type the text to append into Suffix (end of each line); it can also be left blank;
3. Paste your card content into Original Text, one item per line;
4. Click Apply and the result appears on the right, ready to copy or export as a TXT file.

4. Things to keep in mind

• You only need to fill in one of prefix and suffix; a blank field adds nothing on that side;
• Blank lines are also wrapped, so if your input contains blanks, clean them with Trim Spaces & Blank Lines first;
• The tool only appends to the start and end of each line; the middle of a card is never touched and the original text stays in the left input box;
• All processing happens locally in the browser; nothing is uploaded.
