Adding both a prefix and a suffix to every line (e.g. quotes and commas) usually means doing it by hand or with a script. The Prefix and Suffix Text Lines tool does it in the browser: paste your list, set prefix and suffix, and every line is wrapped—no sign-up and no data sent to a server.
What does Prefix and Suffix Text Lines do?
Prefix and Suffix Text Lines is a free online tool that adds the same prefix to the start and the same suffix to the end of every line. You set both strings independently. It is used to wrap lines in quotes and commas, build JSON array strings, or add consistent formatting to each line. All processing runs in your browser; there is no upload, no storage, and no account required.
Key Features
- Prefix and suffix — Each line gets the same prefix at the start and the same suffix at the end. You set both independently.
- Any strings — Use quotes and commas (
" and ,), brackets, or any custom prefix and suffix.
- Any input — Paste or type text with one or more lines. Each line is wrapped with the prefix and suffix. No size limit for in-browser processing.
- Instant result — Paste, set prefix and suffix, and see the result. Copy when ready.
- Privacy-first — All processing happens in your browser. Your text is never sent to any server.
- No account — Use as often as you need without sign-up.
How to Use Prefix and Suffix Text Lines
- Open the Prefix and Suffix Text Lines tool.
- Paste or type your text (one item or value per line).
- Enter the prefix (e.g.
") and the suffix (e.g. ",). View the result. Copy the result.
- Paste into your JSON, config, or doc. Use the "Use tool" button on the docs page if you are reading this from the documentation.
Real Use Cases
- JSON array strings — Wrap each line in quotes and add a comma (e.g. prefix
", suffix ",) to build array items.
- Quoted list — Add quote at start and comma or period at end for a quoted, punctuated list.
- Config or code — Wrap each line in brackets, quotes, or a fixed pattern (e.g.
[ and ]).
- CSV or structured rows — Add a consistent wrapper to each field or line for import or generation.
- Templating — Produce lines in the form
prefix + line + suffix for scripts or templates.
- Markdown or docs — Wrap lines in backticks or other markers for code or emphasis.
Why Use Prefix and Suffix Text Lines Instead of Alternatives?
- vs. Manual wrap — No need to add prefix and suffix to each line by hand. One paste, set both, copy.
- vs. Prefix only or suffix only — Use Prefix Text Lines or Suffix Text Lines when you need only one. This tool does both in one step.
- vs. Find-and-replace — Simpler when you want one fixed prefix and one fixed suffix per line.
- vs. Scripts — No coding. Works in any browser.
Each line gets prefix at the start and suffix at the end. If you have one long line, split into lines first (e.g. split by comma with Split Strings), then add prefix and suffix.
Benefits for Developers, Data Users, and Writers
- Developers — Quick JSON array items or config lines. No one-off script.
- Data users — Build structured rows or quoted lists from a plain list.
- Writers — Wrap list items in quotes or markers in bulk.
Common Mistakes
- Prefix and suffix on the same line — Each line gets prefix at the start and suffix at the end. If you have one long line, split into lines first (e.g. split by comma), then add prefix and suffix.
- Wrong order — Prefix is always at the start of each line, suffix at the end. The tool does not reorder.
- Forgetting to copy — The result is not saved. Copy before closing the tab or refreshing.
