Filtering text to lines that match a word

What the Text Filter Does and How

The Text Filter filters your text by line, keeping only the lines that contain a word, or removing them, as you choose. You type or paste your text, and the tool produces the converted version live, so you can see and copy the result as you work. You type a word or phrase and choose whether to keep or remove lines containing it, and the tool filters your text line by line as you type.

The conversion runs the moment you type, with no button to press. For example, a list with some matching lines becomes only the lines you want. The output sits beside your input, so you can compare the two and adjust your text if needed.

The result updates live as you type. There is no button to press: the text filter converts your text the moment you type or paste it, and the Copy button puts the result on your clipboard ready to use.

Filtering text keeps or removes lines based on a word or phrase. It is useful for pulling out matching lines from a list or log, or stripping out lines you do not want, in one step.

Everything runs in your browser, so your text is never uploaded and the result appears instantly and privately. The tool works the same on a phone, tablet or computer, with no account and no limit on how much text you can convert.

Check the result before copying. Glance at the output to confirm it looks the way you expect before you copy it, especially for text with unusual punctuation or symbols.

Convert as much as you need. There is no limit, so you can convert a single word or a long passage. The result updates live however much text you paste in.

Use it as part of your workflow. Keep the tool open while you work, converting text on the fly and copying each result into place as you go.

Common Mistakes to Avoid

Expecting a different result than the tool gives. The tool filters your text by line, keeping only the lines that contain a word, or removing them, as you choose. It transforms your text exactly as described, so check that this is the change you want before using the result.

Copying before checking. It is easy to copy the result without glancing at it. A quick check catches any input typo before you paste the converted text into place.

Pasting into the wrong place. The converted text is only useful where its new form is wanted. Make sure you paste it where the changed case or format is what you need.

Assuming it edits your original. The tool produces a new converted version and leaves your input as you typed it. It does not change your original document; you copy the result and paste it yourself.
