Number to Words Converter

WHAT IT DOES

Number to Words Converter transforms numeric values into their word equivalents. Enter 123 and get "one hundred twenty-three" or "One Hundred Twenty-Three" with capitalization. The tool supports integers up to 1 trillion, decimal numbers (e.g., 3.14 → "three point one four"), and currency formats (USD, EUR, GBP). You can customize the output with options like including "and", hyphenation, capitalization, and decimal style (point or fractional). The result can be copied to your clipboard with one click.

WHERE IT RUNS

The extension runs entirely within your browser's local environment using the BotGentz framework. All number parsing, word conversion, and formatting occur on your machine without any network requests. No number data, conversion results, or user activity is ever transmitted, uploaded, or stored externally. The tool works on any website and respects the browser's security boundaries, operating within the isolated extension sandbox. Number-to-words conversion uses pure JavaScript with a lookup table and chunk-based processing.

HOW TO USE

Click the extension toolbar icon to open the Number to Words Converter panel. Enter a number in the input field (e.g., "123", "3.14", "1234.56"). The conversion result appears instantly. Click "Convert" to manually trigger a conversion. Click "Copy" to copy the result to your clipboard. Toggle "Include 'and'" to add "and" before the last part of the number (e.g., "one hundred and twenty-three"). Toggle "Capitalize output" to capitalize the first letter of the result. Toggle "Hyphenate compounds" to hyphenate compound numbers (e.g., "twenty-three" vs "twenty three"). Select the "Decimal Style" (Point or Fractional) to control how decimal numbers are expressed. Select the "Currency" (USD, EUR, GBP) to format the output as currency (e.g., "one hundred twenty-three dollars and forty-five cents"). The panel displays the converted result in a clear, readable format.

THE NUMBER TO WORDS ENGINE — WHY IT WORKS

Most number-to-words converters use simple mapping tables that break on larger numbers or decimal values. This tool uses a chunk-based processing engine that breaks numbers into groups of three digits (thousands, millions, billions, trillions), converts each chunk using a lookup table, and assembles the result with appropriate scale words. The engine handles numbers from zero to 999,999,999,999 (1 trillion minus 1). For decimal numbers, the engine separates the integer and fractional parts and processes them independently. The fractional part can be expressed as individual digits ("point one two three") or as fractional hundredths ("and twelve hundredths"). The currency mode adds the appropriate currency and cent labels based on the selected currency. The "and" insertion uses a smart placement algorithm that adds "and" before the last tens/ones group when the number is greater than 100 and has a remainder. This chunk-based approach ensures accurate, readable output for any number within the supported range.

THE PANEL

The Number to Words Converter panel is fully draggable by its title bar and remembers its position on screen per website. It snaps to the edges of your browser window for clean alignment. Collapse the panel to a compact icon strip using the minimize button, restoring it with a single click. Resize the panel by dragging any edge or corner; the input area, output display, and controls adjust proportionally. Press the Escape key to close the panel instantly. The panel maintains independent state for each browser tab, allowing you to convert numbers in multiple tabs simultaneously.

PLEASE NOTE

This extension requires the free BotGentz extension framework to be installed and enabled. The tool supports numbers up to 999,999,999,999 (1 trillion minus 1) due to the short scale naming convention. Decimal numbers are supported with the fractional part expressed as digits or hundredths. The currency format assumes two decimal places for cents. The "and" insertion follows common English usage and may not match all regional conventions. All conversion data is processed locally and is never transmitted, logged, or shared. The extension requests no network permissions and functions entirely offline. The source code is fully auditable and available for review.
