How to use Generate Symbolic Numbering

  1. 1. Set count and starting point. Enter How many numbers and Start from to control how many alphabetic labels appear and where the sequence begins, following the bijective base-26 pattern.
  2. 2. Choose the letter case. Turn on Uppercase letters for a style like A, B, C, matching spreadsheet column headers, or leave it off for lowercase a, b, c.
  3. 3. Choose a separator. Set Separator to a comma or newline depending on whether the labels are going into a numbered outline or a column reference list.
  4. 4. Copy the labels. Copy the generated alphabetic sequence into a spreadsheet template, outline or labeling system.

When to use Generate Symbolic Numbering

Generate Symbolic Numbering produces the letter-based counting sequence used for spreadsheet columns, a, b, c through z, aa, ab and beyond in bijective base 26. Use this tool instead of manually working out what comes after column z when building a reference or template.

  • Mapping spreadsheet column letters to numbers. A script that converts between column letter and column index needs a reference list past column z, like aa and ab, to verify its bijective base-26 conversion logic.
  • Labeling outline sub-points with letters. A formal document's third-level outline uses lowercase letters, a, b, c, for sub-points, so generating a run of them saves manually typing each label.
  • Naming a series of test cases or variants. A design system documenting component variants wants to label them Variant A, Variant B and so on, so generating uppercase letters gives a ready-made naming sequence.
