# From Base32

Base32 is a notation for encoding arbitrary byte data using a restricted set of symbols that can be conveniently used by humans and processed by computers. It uses a smaller set of characters than Base64, usually the uppercase alphabet and the numbers 2 to 7. From Base32 lives in the **Data format** category of the `fx` menu. See [Base32](https://datatracker.ietf.org/doc/html/rfc4648#section-6) for format details.

## Parameters

| Parameter                 | Type    | Required | Default   | Description                                            |
| ------------------------- | ------- | -------- | --------- | ------------------------------------------------------ |
| Input                     | string  | yes      | —         | Value to transform. Previous step output or a literal. |
| Alphabet                  | string  | no       | `A-Z2-7=` | Argument value for this operation.                     |
| Remove non-alphabet chars | boolean | no       | `true`    | Enabled by default.                                    |

`Input` is the primary value (previous step output or a literal).

## Returned value

| Type     | Description                               |
| -------- | ----------------------------------------- |
| `string` | Result of the From Base32 transformation. |

## Limitations

- Invalid or mismatched encoding for the chosen options typically raises an evaluation error — fix the Input or options before re-running.

## Example

<summary>Run From Base32</summary>

Base32 is a notation for encoding arbitrary byte data using a restricted set of symbols that can be conveniently used by humans and processed by computers. Adjust optional parameters when the defaults do not match your payload.

1. Set **Input** to the value to transform (previous step output or a literal).

2. Review **Alphabet**, **Remove non-alphabet chars** and keep defaults unless your format requires otherwise.

3. Confirm **Output value** shows the transformed result.
