Sample data to guess gender by name

The columns highlighted in yellow are input columns, i.e. the name of a person.

The ones highlighted in green are output columns, i.e. the first name of the person and the gender of the person.

Tab 2: Database of all names and their most likely gender

This Google Sheet contains a tab called ‘Database’ where all the information about a name and its gender is stored.

The Guessing Gender tab pulls information from the Database tab to guess the gender of the person based on their first name. It also comes in handy to add gender information for a new name or edit gender information to Unisex, as and when needed.

How to use Google Sheets to guess the gender of a name in a spreadsheet

If you are using Excel, you can simply create a copy of this Google Sheets document and update the formulas to make it work in Excel. Alternatively, you can import your list in Google Sheets, run the calculations in Google Sheets, and then export a CSV or an XLSX file again.

Running the calculations in Google Sheets


  • If the guessed gender is ‘Unisex’, or appears to be the opposite of what you thought, use column E, Manual Correction, to update it.
  • If column D, Guessed Gender, doesn’t guess anything, you can add those values in column C, First Name, at the end of the tab: Database in column A, First Name, and add Gender information in column B, Gender. The tab will automatically update the gender information for these names for which the value in the Gender column was previously missing.
