1. SQL IN Clause Generation
Wrap a column of values with ' prefix and ', suffix to build SQL WHERE id IN ('val1', 'val2', 'val3') clauses from raw data exports or spreadsheet columns — a daily developer productivity task.
2. HTML/JSX List Generation
Wrap plain text items with <li> and </li> HTML tags — or <ListItem> and </ListItem> React component tags — to scaffold component trees from product requirement documents or spreadsheets.
3. JavaScript Bulk Import Statements
Turn a list of exported component names into import ComponentName from './components/ComponentName'; lines in bulk — then paste the whole block into your barrel export file.
4. Markdown & Documentation Formatting
Convert plain item lists into Markdown bullet lists (- item), numbered lists (1. item), or checklist items (- [ ] item) by setting the appropriate prefix. Paste directly into your .md file.
5. Shell Scripting & Command Generation
Prefix a list of filenames with rm to generate deletion commands, or with chmod +x to generate permission commands. Pipe the output directly into your terminal session.
6. Data Engineers & ETL Pipelines
Fix unquoted CSV columns by wrapping field values with double quotes, or add column-specific prefixes before loading into data transformation pipelines.
Can I add text to only specific lines?
This tool adds prefix/suffix to all lines. To target only specific lines, first use the Filter Lines tool to isolate the lines you want, apply the prefix/suffix transformation, then manually combine with your remaining lines.
Does it handle Windows-style CRLF line endings?
Yes — the tool automatically normalizes both CRLF (\r\n, Windows) and LF (\n, Unix/Mac) line endings before processing. Pasted Windows text is handled correctly regardless of your operating system.
How many lines can this process at once?
Processing runs in your browser's JavaScript engine — practically unlimited. The tool has been tested with 200,000+ line files without performance degradation. Results appear in real-time as you type.
Can I add sequential line numbers as a prefix?
For static prefixes, you can manually type a number. For dynamic auto-incrementing line numbers, enable the "Line Numbers" toggle in the tool settings, or use the Repeat Text tool with line numbering enabled.
Can I use special characters like quotes or backslashes in prefix/suffix?
Yes — you can type any character directly into the prefix/suffix fields: single quotes ('), double quotes ("), backslashes (\), backticks (`), angle brackets (< >), and Unicode characters are all treated as literal characters.
