FAQ

  1. Can Line Affixer handle large amounts of text?

    Yes, Line Affixer can process hundreds of lines simultaneously since it operates client-side in your browser. However, for very large datasets (thousands of lines), you may notice a slight delay.

  2. How do I add custom numbering patterns?

    Use the {n} placeholder in your prefix or suffix pattern. For example, "Item_{n}" will create "Item_1", "Item_2", etc. You can also set custom numbering sequences in the numbering options.

  3. Does Line Affixer preserve the original text formatting?

    Yes, Line Affixer maintains the original text structure and only adds the specified prefixes and suffixes. Line breaks and spacing are preserved.

  4. How do I add both numbers and text to each line?

    Combine text and the {n} placeholder in your prefix or suffix. For example, "Section {n}:" as prefix will add "Section 1:", "Section 2:", etc. to your lines.

  5. Can I use special characters in prefixes and suffixes?

    Yes, Line Affixer supports all ASCII characters including special characters and symbols in both prefixes and suffixes.
