A PRACTICAL GUIDE

How to use the Spreadsheet Formula Generator.

Formula generation works best with column names and expected results. Choose Excel or Sheets and include examples of blanks or errors.

Make the workflow fit your task.

Describe the calculation in ordinary language, map each input to a column and supply two rows with known answers. Generate a formula for your spreadsheet application, then test blanks, numbers stored as text and copied references before filling a column.

Illustrative input and output · a teaching example, not a live WebAct run

Example input

Excel or Google Sheets, English function names and comma separators. A2:A4 = Paid, Unpaid, Paid. B2:B4 = 10, 20, 5 as numbers. Sum only Paid amounts.

Completed example

=SUMIF(A2:A4,"Paid",B2:B4)

Expected result: 15, from 10 + 5. The Unpaid row contributes nothing. Adapt separators for your spreadsheet locale.

Decisions and troubleshooting.

Should a generated formula use entire columns or bounded ranges?

Whole columns can simplify expanding data; bounded ranges or tables make scope explicit. Choose based on the workbook size and how new rows arrive.

Why does SUMIF return zero when matching rows exist?

Inspect spaces in the criteria column and whether amounts are numeric. A visually correct currency string may still be text.

Try it with your own source.

Replace the example with your material in the task prompt. Keep the requirements you need, then copy the task into WebAct.
