Every Text Tool You Actually Need

Switch between 18+ transformations from the tool bar above. Each tool is purpose-built — not an afterthought wrapped in a generic textarea.

Case Converters

8 case styles in one click

Convert any text to Lowercase, UPPERCASE, camelCase, Sentence case, Title Case, Capitalized Case, AlTeRnAtInG CaSe, or Inverse Case instantly. Ideal for code refactoring, content formatting, and fixing accidental CAPS LOCK text.

Text to Array

Custom separator · Typed output

Split any text into a developer-ready array using any separator — comma, pipe, newline, or a custom string. Choose your output datatype (String, Number, Boolean) and optionally filter with 'Except Types' to produce mixed-type arrays for real codebases.

Substring Replacer

Whole-word control · Case-sensitive

Advanced find-and-replace with three modes: Replace All, Replace First, or Replace Last. Toggle 'Match whole words only' to avoid partial hits, and 'Case-sensitive' for precise substitutions — far more powerful than a basic Ctrl+H.

Duplicate Word Remover

Clean repetitive text instantly

Automatically detect and strip duplicate words from any block of text. Essential for cleaning scraped data, normalizing keyword lists, or sanitizing user-generated content before storage or display.

Word Frequency Counter

Ranked occurrence analysis

Analyze any text and get a ranked breakdown of how often each word appears. Useful for SEO keyword density checks, corpus analysis, identifying overused terms in long-form writing, and data preprocessing.

Sort Words

Alphabetical or custom order

Sort individual words or lines alphabetically (A–Z or Z–A). Perfect for normalizing tag lists, sorting CSV columns, alphabetizing glossaries, or preparing data for deduplication pipelines.

Repeat Text Generator

Bulk text multiplication

Generate repeated copies of any string or paragraph a specified number of times. A time-saver for creating test data, populating placeholder content, stress-testing UI layouts with long strings, and generating dummy datasets.

Character & Substring Tools

Remove · Find · Replace · Reverse

A suite of precision tools: Character Remover strips unwanted characters by pattern, Remove Substring deletes specific sequences globally, Find & Replace handles targeted substitutions, and Reverse Text flips any string character-by-character or word-by-word.

How to Use the Text Converter

  1. 01

    Select a Tool

    Click any tool button in the SELECT TOOL toolbar at the top — Case converters, Text to Array, Substring Replacer, Duplicate Remover, Word Frequency Counter, and more. The active tool is highlighted and its settings panel appears instantly below.

  2. 02

    Paste or Type Your Text

    Enter your text in the input area. The conversion updates in real time as you type — no button press needed. Toggle between Single view (stacked) and Multi view (side-by-side) from the Layout mode bar to compare input and output simultaneously.

  3. 03

    Configure Tool Options

    Each tool exposes its own settings: set a custom separator for Text to Array, choose a datatype (String / Number / Boolean), toggle case-sensitivity or whole-word matching for Substring Replacer, or pick a sort direction for Sort Words.

  4. 04

    Chain or Copy

    Click 'Apply Output as Current Input' to feed the result back into the input and apply a second transformation — enabling multi-step pipelines without copy-pasting. When done, copy the output or download it as a text file.

Text to Array: How the Datatype Engine Works

Most text-to-array tools only output strings. This tool goes further — it lets you control the output datatype per element so the array is copy-paste ready for your actual code.

SettingInputOutput
Stringapple, banana, cherry["apple","banana","cherry"]
Number1, 2, 3, 4, 5[1,2,3,4,5]
Booleantrue, false, true[true,false,true]
Custom + Exceptalice, 42, true["alice",42,true]

Except Types: When Custom datatype is selected, toggle String / Number / Boolean in the Except Types panel to keep those types unquoted while the base datatype wraps everything else — producing realistic mixed-type arrays without manual editing.

Real-World Examples

See how different users get value from the text converter in their daily workflows.

DeveloperText to Array
INuser_first_name, user_last_name, email_address
OUT["user_first_name","user_last_name","email_address"]

Paste a CSV header row, set separator to comma → get a typed JS string array, ready to destructure.

Content WriterTitle Case
