Excel column & value counter

Turn Excel column letters into numbers, count columns in a range, and count values with a ready COUNTIF formula.

Column BB = 54

Whole-column reference: BB:BB

Excel's last column is XFD (16,384). Google Sheets uses the same letters.

How many columns between two letters?

25 columns

BB (54) to BZ (78), counting both ends. Range reference: BB:BZ

Everything runs in your browser. Your data never leaves your device. “GCash” and “Gcash ” count as different values unless you tick the trim and case options.

Two spreadsheet questions, answered fast

Spreadsheets run a lot of digital work: client trackers, remittance logs, expense sheets, order lists. Two small questions come up again and again. What number is column BB? And how many times does a value appear in a column? This tool answers both in seconds, so you can write the right formula the first time.

How to use it

On the first tab, type column letters to get the number, or type a number to get the letters. You can also count how many columns sit between two letters, counting both ends. On the second tab, paste one column copied from Excel or Google Sheets. You get the total, blanks, distinct values, duplicates, a frequency table, and a ready COUNTIF formula for any value you click.

Common formulas

For clean results, trim spaces and keep spelling consistent. “GCash” and “Gcash ” are different values unless you tick the trim and case options. Pair this with the case converter to tidy a list first.

Questions

What number is column BB in Excel?
Column BB is number 54. Letters work like a base-26 count: A to Z is 1 to 26, AA is 27, and BB is 2 × 26 + 2 = 54.
What is the last column in Excel?
XFD, which is column 16,384. Google Sheets uses the same letters, but its limit depends on the sheet.
How do I count how many columns are in a range?
Subtract the two column numbers and add 1. From BB (54) to BZ (78) that is 25 columns. The tool does this and shows the range reference.
Is my data uploaded anywhere?
No. Everything runs in your browser and your pasted data never leaves your device.
Why does COUNTIF count “GCash” and “gcash” together?
Excel’s COUNTIF ignores letter case. It does not trim spaces, so “GCash ” with a trailing space is counted separately. Trim your data first if that matters.
