Use case
Help spreadsheet users comparing AI formula tools choose a narrow formula helper when the job is to write, understand, or repair one formula rather than analyze an uploaded workbook.
Use this page when you are comparing AI spreadsheet formula generators and the job in front of you is still formula-shaped: write one formula, explain one inherited formula, fix one broken formula, or create a custom rule for conditional formatting or data validation.
Do not use Write My Formula as a replacement for tools that upload whole workbooks, chat with data files, build dashboards, generate charts, or automate full spreadsheet workflows. It is intentionally narrower so the formula, explanation, and paste checks stay visible.
For email addresses in column A, a Google Sheets formula can extract the domain while leaving blank rows empty.
=IF(A2="","",REGEXEXTRACT(A2,"@(.+)$"))
The formula checks for a blank first, then extracts the text after @ from nonblank email addresses. The checks tell you to test missing @ symbols and blank rows before filling down.
