What is Answer Piping?

Answer Piping allows you to automatically insert (or "pipe") a respondent’s previous answer into a later question. This creates a personalized, conversational flow that makes surveys feel more engaging and relevant to the participant.

Key Capabilities

  1. Intra-Survey Piping: Use an answer from Question 1 to customize the text in Question 5 of the same survey.

  2. Cross-Survey Piping: Pull responses from a previously completed survey into a brand-new one for the same participant.

Supported Question Types

Answer Piping is compatible with the following question formats:

  1. Single Selection

  2. Dropdown

  3. Text

  4. Rating

Example in Practice

  1. Question 1: "What is your favorite hobby?" (Respondent types: Rock Climbing)

  2. Question 2 (Piped): "How many years have you been practicing Rock Climbing?"

Benefit

Personalizing questions with Answer Piping reduces "survey fatigue" and increases completion rates by making the experience feel like a relevant, one-on-one conversation.

Setting up Answer Piping Within the Same Survey

1. Create your source question: Set up a question with predefined options or enable the 'OTHER OPTION' to allow for custom text entries.

Q4 What are you doing right now? in the survey builder with five choices: Working, Excercising, Watching TV/movies, Relaxing, and Other

Enable the 'OTHER OPTION' toggle so participants can type a custom response. The piped text will include whatever they enter.

The same question scrolled down to show the Other Option toggle enabled, allowing participants to provide custom text

2. Enable Piping: Create the subsequent question where you want the answer to appear. Locate and toggle on the Piping option.

Note

You do not need to leave a manual blank space in your question text for the piped response; the system handles the spacing automatically.

Q5 Did you eat a meal in the past 2 hours? selected in the sidebar, with the PIPING section showing the Insert Text from a Previous Question toggle enabled and an Insert Question Response button

3. Configure the Source: In the Piping modal, select 'Current Survey' and choose the specific question (e.g., Question 4) you wish to pull data from.

The Insert Question Response modal on the Current Survey tab with Source Question set to Q4 What are you doing right now?, Token Type set to Choice Text, and the generated token {{Q://Q4/ChoiceTextEntryValue}}

4. Verify the Placeholder: A tag like {{Q://Q4/ChoiceTextEntryValue}} will appear in your question editor. This placeholder will be replaced by the participant's actual answer during the live survey.

Q5 Did you eat a meal in the past 2 hours? in the question editor with the piping placeholder {{Q://Q4/ChoiceTextEntryValue}} below the question text, and Yes/No choices with Pre-Fill Choices enabled

Mobile App View — Same Survey

1. Standard Selection: If a participant selects "Relaxing," that specific phrase will appear in the next question.

The KB Screenshots survey on the ExpiWell mobile app showing question 4 of 9, What are you doing right now?, with Relaxing selected from five choices
Question 5 of 9 on the mobile app, Did you eat a meal in the past 2 hours?, with the piped answer Relaxing shown below the question text and Yes/No choices

2. Custom "Other" Input: If a participant selects "Other" and types their own response (for example, "Cooking"), the system will seamlessly pipe that custom text into the follow-up question.

Question 4 of 9 on the mobile app with the Other choice selected and the custom text Cooking typed into the free-text field below
Question 5 of 9 on the mobile app, Did you eat a meal in the past 2 hours?, with the custom Other response Cooking piped in below the question text and No selected

Setting up Answer Piping Across Surveys

1. Identify the Source Survey: Ensure your initial survey question is one of the four compatible question types (Single Selection, Text, Rating, or Dropdown). In this example, it would be a Text question, Question 1 from the 'Monthly Fitness Goal' survey.

The Monthly Fitness Goal survey with Q1 What is the fitness goals for this month? as a Text Entry question, showing the question editor, Input Type set to Text, Logic, and Piping sections

2. Enable Cross-Piping: In your second survey, open the question where you want the earlier answer to appear and toggle on the Piping option, then click Insert Question Response.

3. Connect the Surveys: In the Piping modal, select 'Another Survey.' Choose the source survey and the specific question you want to reference (e.g., Question 1 of the 'Monthly Fitness Goal' survey).

The Insert Question Response modal on the Another Survey tab with Source Survey set to Monthly Fitness Goal, Source Question set to Q1 What is the fitness goals for this month?, and the generated cross-survey piping token

4. Confirm the Connection: The system inserts a placeholder tag into your question text. During the survey, the participant's answer from the first survey automatically populates here.

Mobile App View — Across Surveys

Dynamic Personalization: A goal entered in the 'Monthly Fitness Goal' survey (e.g., "Lose 1kg fat") will appear in the next survey the participant takes, providing context without asking them to repeat themselves.

The Monthly Fitness Goal survey on the ExpiWell mobile app showing question 1 of 1, What is the fitness goals for this month?, answered with the text Lose 1kg fat
Question 6 of 10 in the KB Screenshots survey on the mobile app, What time did you eat?, with the goal Lose 1kg fat piped in from the Monthly Fitness Goal survey

Handling Empty Responses: If a participant skips the source question, the piped area displays a blank line instead of text.

Note

To avoid awkward phrasing, consider setting your source questions to "Force Response" if you plan to pipe those answers later.
