How do you filter lines of text?

A text filter keeps or removes the lines that match a search term, working line by line. Snabbit supports plain substring matching, optional case-insensitivity, and full regular expressions, letting you extract or strip lines that contain a pattern. It runs entirely in your browser, so the text you filter is never uploaded to a server.

How to use the Text Filter

1 Paste the lines you want to filter.
2 Enter a word or regular expression to match.
3 Choose to keep or remove matching lines, with optional case settings.
4 Copy the filtered lines.

What you can use it for

Extracting log lines that contain an error.
Removing comment or blank lines from a list.
Filtering a list down to matching entries.
Stripping unwanted rows before processing.

Frequently asked questions

What is the difference between keep and remove?

“Keep matching” outputs only the lines that contain your pattern, like grep. “Remove matching” outputs everything except those lines, like grep -v.

Can I use a regular expression?

Yes. Enable the Regex option to match with a full regular expression. If the pattern is invalid, the tool safely falls back to a literal substring match.

Is matching case-sensitive?

By default, yes. Turn on “Ignore case” to match regardless of capitalisation in both substring and regex modes.
