CSV Formula Generator

Append a formula column to a CSV file using a formula template and row placeholder. Generate formulas for each data row, then download and open the CSV in a spreadsheet.

Tool guide

CSV Formula Generator: what it does

Enter a new column heading and a formula containing {row}. The placeholder is replaced with each spreadsheet row number, accounting for the header in row 1. For example, =A{row}+B{row} becomes formulas such as =A2+B2.

How to use it

Choose a CSV and edit the formula template before running the tool. Check the generated formulas in your spreadsheet application; CSV stores formula text and the behavior depends on how the receiving application interprets it.

What to check in the result

The generator does not calculate formulas or verify referenced columns. Only use formulas from trusted sources because spreadsheet applications may execute formulas when a CSV is opened.

Frequently asked questions

Does this calculate the result?

No. It writes formula text for a spreadsheet to calculate.

How does the row placeholder work?

It is replaced with the data row number, starting at 2 below the header.

Are formulas supported by every CSV reader?

No. CSV is plain text, and formula behavior depends on the application opening it.
