Overview

Lines to JS Array converts newline-separated entries into a JavaScript array literal with proper escaping and indentation. Perfect for prototyping UI lists, seeding fixtures, or producing quick configuration snippets.

How to Use

Paste multi-line text
Each non-empty line becomes a separate array element. Empty lines are ignored automatically.
Generate the array
Click Generate to build a double-quoted array with escaped characters and two-space indentation.
Copy the formatted output
Paste the array into editors, code reviews, or automation scripts as needed.

Use Cases

Bootstrap front-end prototypes

Transform plain text into array literals for select menus, tab definitions, or feature flags without writing boilerplate.

Generate fixtures for automated tests

Convert sample data into arrays ready for Jest, Vitest, Cypress, or Playwright fixtures.

Compose JSON and TypeScript snippets

Turn multi-line notes into arrays before embedding them in JSON payloads, TS configs, or migration scripts.

Share structured data in documentation

Publish pre-formatted arrays in READMEs, runbooks, or onboarding guides without manual formatting.

Frequently Asked Questions

How are quotes handled?

Any double quotes inside your lines are escaped automatically to keep the literal valid.

Are empty lines included?

No. Empty lines are skipped so the array only contains meaningful entries.

Can I change the indentation?

The tool emits two-space indentation by default. After copying you can apply project-specific formatting with Prettier or your editor.

Concept Notes

From raw notes to valid literals

Turning a note dump into an array literal is more than wrapping items in brackets: embedded quotes, backslashes, and commas must be escaped so the string parses, and preserving the original line order keeps downstream mappings predictable. Cleaning the text once here means you can paste fixtures, menu labels, or seed data directly into code without a second pass through a formatter.
