Numbering in the format of [000X] with leading zeros

I am trying to build a numbering format that uses up to three leading zeros, which is possible in the Word GUI.

I have gotten close with this format:

	{
      reference: 'numbering',
      levels: [
        {
          level: 0,
          format: 'decimalZero',
          text: '[00%1]',
          alignment: AlignmentType.LEFT,
          suffix: LevelSuffix.NOTHING
        }
      ]
    }

But it fails at 100+ going to [00100] rather than [0100]

I found in the spec that it says there is a format attribute that:

Specifies a custom format using the XSLT format attribute. For example, a value of &#x30A2 indicates that Katakana numbering should be used.

Does docx allow for custom formats? Is there another method that I’m missing?

Exactly. Thanks so much for your help though! I appreciate you reaching out 😄

Yeah, I think you’re right. That makes a lot of sense. Basically you’re passing ‘000%1’ in and then the %1 is being replaced with the current number.
