What is a Word Splitter Tool?
A Word Splitter Tool is designed to break down text into its individual components—typically words—and provide various ways to process, filter, and export them. Whether you're analyzing vocabulary, preparing data for machine learning, or simply need a clean list of words from a document, this tool handles it instantly. If you need to split text by commas or other custom characters, use our Split Text Tool instead.
Unlike text editors that split manually, this tool automates the entire process. Extract every word, remove duplicates, filter empty entries, and export in formats like lists or JSON arrays—all with a single click.

Frequently Asked Questions
How do I split text into words?
Simply paste your text into the input area. The tool defaults to 'Split by Space', which automatically breaks your text into individual words. Each word will appear on a separate line in the output. You can then copy the list or download it as a file.
Can I remove duplicate words from my text?
Yes! Enable the 'Remove Duplicates' checkbox in the Filters section. This will keep only unique words, perfect for finding how many distinct words are used in a document or building a vocabulary list. The statistics panel will show you both the total word count and unique word count.
How do I export my word list as JSON?
In the 'Output Format' section, select 'JSON Array'. The tool will format your word list as a proper JavaScript/JSON array like ["apple", "banana", "cherry"]. This is perfect for developers who need to use the word list in code, APIs, or databases.
What is batch mode and when should I use it?
Batch mode processes your text line-by-line instead of as one continuous block. Enable it when you have multiple sentences or items (one per line) and want to split each line independently. For example, if you have a list of product descriptions and want to extract words from each description separately.
Can I use regex patterns to split words?
Yes! Select 'Regex' as your split method and enter a custom regex pattern. For example, use [^a-zA-Z]+ to split on anything that isn't a letter (removes punctuation and numbers). Use \\d+ to split wherever numbers appear. This gives you powerful control over exactly how text is split.
Is my data safe and private?
Yes, 100% safe. This tool runs entirely in your web browser using client-side JavaScript. Nothing you type or paste is ever sent to our servers or stored anywhere. It works completely offline after the page loads, making it secure for sensitive documents, private notes, or confidential text.
Can I upload files to extract words?
Yes! Click the 'Upload' button to load text files (.txt, .md, .csv, .log, .json) directly. The tool can handle files of several megabytes in size. After uploading, configure your splitting and filtering options, then download or copy the results.
How can I use this for SEO keyword research?
Paste content from competitor pages or your own content. Use 'Split by Space' to extract all words, then enable 'Remove Duplicates' to see unique keywords. Export as a list to analyze keyword density or find commonly used terms. This helps identify keyword gaps and content opportunities.
What's the difference between 'Trim Whitespace' and 'Remove Empty'?
'Trim Whitespace' removes spaces from the beginning and end of each word (e.g., ' hello ' becomes 'hello'). 'Remove Empty' filters out completely blank entries that might result from multiple spaces or delimiters in a row. Both are usually enabled for cleaner results.
Can I see the original text and word list side-by-side?
Yes! Click the 'Compare' button to enable comparison mode. This displays your original text on the left and the extracted/filtered word list on the right, making it easy to verify the results and see exactly what was extracted.
