Text filter tool What is a text filter?
With this tool you can filter text lines. You can do two ways of filtering – the first way allows you to find and display all text lines that match contain the given search pattern. This pattern is simply a subtext of original text, which can be one or more characters, numbers, words or phrases. The second way is to use a regular expression. You can also select the reverse mode that will display all lines that weren't matched. Textabulous!
Text filter examples Click to use
Find Facts About Apples
In this example, we filter text using a text template. This example loads a bunch of facts about fruit and only returns those text lines that have words containing "pple" in them. These words are "Apple" and "apple".
A banana contains 75% water. The most consumed fruit in America is the banana Bananas are a good source of vitamin C, potassium and fiber. Fresh apples float because they contain 25% air. Bananas contain no fat, cholesterol or sodium. There are over 7,000 different types of apples. One plain milk chocolate bar has more protein than a banana. Banana plants can grow as high as 20 feet (6 meters) tall. Apples are more effective at waking you up in the morning than coffee.

Reverse Filtering
In this example, we demonstrate the reverse filter mode. This mode returns all lines from the given text that do not contain the given text pattern. We load a set of data that describes the area and population in all seven continents, then we enable the reverse-filter mode and set the match pattern to the word "population". As a result we get back all the data excluding population count.
Africa: - area: 30,370,000; - population: 1,287,920,000; Antarctica: - area: 14,000,000; - population: 4,490; Asia: - area: 44,579,000; - population: 4,545,133,000; Australia: - area: 8,600,000; - population: 41,261,000; Europe: - area: 10,180,000; - population: 742,648,000; North America: - area: 24,709,000; - population: 587,615,000; South America: - area: 17,840,000; - population: 428,240,000;
