# Questions & Variables

> Reusable question actions, multi-language variables, CSV import/export, per-user variables tab

**Variables** are reusable question actions — write a question once, use it across many challenges. Member answers are stored on their profile as mapped variables and surface in analytics and integrations.

## Variable types

Same shapes as question actions (see [Question Actions](/admin-guide/challenges/question-actions)):

* Multiple choice (quiz or non-quiz)
* Single choice
* Free text
* Rating / NPS
* Select-value-in-range
* Select-from-list
* Secret code

***

## Creating a variable

Settings -> Questions & Variables -> Add. Fill out the question, options (if applicable), and save. Available for use in any challenge's Content step (#974).

***

## Multi-language variables

Variables support translations (#1171) — same translation editor as other content. Members see the variable in their chosen language.

***

## CSV import & export

For bulk variable management (e.g. a large trivia bank or product lookup):

* **Import** (#761) — upload a CSV of questions with options and answer keys.
* **Export** (#756) — download your existing variables for audit or translation outsourcing.

***

## Per-user answers (Variables tab)

On any member's profile, the **Variables / Questions tab** (#1578) shows every variable they've answered with their response. Useful for:

* Customer support context
* Personalisation ("you said you like X, here's a reward")
* Segmentation for reward drops

See [User Profiles](/admin-guide/user-management/user-profiles).

## Best practices

<Tip>
  Use variables for **questions you'll ask in many challenges** — e.g. "how satisfied with this purchase", "favourite product category". Per-challenge unique questions should be actions, not variables.
</Tip>

<Tip>
  Variables are perfect for **progressive profiling** — ask one new question per challenge and slowly build a full member profile over the first 10 interactions.
