Text / Data Piping

📋 What is text / data piping ?

Text piping allow you to insert a text value called a pipe tag in any of your survey text elements, invitation messages or completion alerts that will get replaced while running the survey with dynamic content to give the respondent the feeling that the survey has been tailored only for him.
You could for example ask the respondent for his name and then re-use his name anywhere in your survey to make it more personal.

➕ Insert a pipe tag

Pipe tags can selected anywhere using the pipe tag selector icon.

🚰 Pipe a text from an answer

Piping from an answer allows you to pipe any text based value entered by the respondent anywhere into your survey.
To pipe the entered answer value you must first set the pipe alias of the answer in the answer properties. Once this is done you can either select the pipe tag using the pipe tag selector or using following tag [[youranswerpipealias]]. This pipe tag will be replaced at runtime while the respondent takes the survey with the actual respondent answer.

🚰 Pipe question selections answers

You may also pipe the selected answers (radio buttons, checkboxes) of a question. To pipe the selected answer of a question you must first set the pipe alias of the question in the question properties. Once this is done you can either select the pipe tag using the pipe tag selector or using following tag [[yourpipealiasquestion]].
