snakecase helper

Tom Santiago
Updated

Converts a string into snakecase format by replacing spaces, dashes, and other non-word characters with underscores (_). Use it when you need consistent identifiers, especially for systems that prefer underscore naming conventions.

Usage

{{snakecase value}}

  • value (required): input string

Examples

  1. Convert a product label to snakecase

    {{snakecase record.product.label}}

    Input:

    {
  "record": {
    "product": {
      "label": "a-b-c d_e"
    }
  }
}

    Output:

    a_b_c_d_e

  2. Convert descriptive text

    {{snakecase record.category}}

    Input:

    {
  "record": {
    "category": "New Product Launch 2025"
  }
}

    Output:

    new_product_launch_2025

  3. Convert camelCase (and other case splitting)

    {{snakecase record.userAction}}

    Input:

    { "record": { "userAction": "getUserProfile" } }

    Output:

    Get_user_profile

Tip

  • All separators are normalized into a single underscore.

  • Useful for generating consistent keys, database field names, or API parameters.

  • Consecutive non-word characters collapse into a single underscore.

  • Output is lowercase and splits camelcase/pascalcase at capital letter boundaries.

  • Digits are preserved; underscores are not inserted between letters and adjacent digits unless a separator exists.

  • Non-string datatype inputs (like numbers or boolean) are converted to strings before processing. Arrays of primitive types (like strings or numbers) are converted into a comma-separated string before processing. If inputs are objects or object arrays, the output will be unusable.
