What is Excel Formulas?

Half of Excel questions are really formula-syntax questions. This free generator writes the formula for you using your actual cell ranges: modern XLOOKUP and classic VLOOKUP, conditional sums and counts with SUMIFS and COUNTIFS, error handling with IFERROR, text joining and splitting, duplicate flagging, date differences with DATEDIF and NETWORKDAYS, ranking, and percentage change. Each output includes both the modern Excel 365 version and a classic-compatible alternative where they differ.

Frequently asked questions

Is this Excel formula generator free to use?

Yes — this Excel formula generator is completely free with no signup, no limits, and no watermarks. Use it as often as you like.

Should I use XLOOKUP or VLOOKUP?

Use XLOOKUP if your Excel supports it (365 / 2021+): it searches any direction, defaults to exact match and takes a built-in fallback value. VLOOKUP only looks right, counts columns by index and breaks when columns move — keep it only for compatibility with older workbooks.

Is my data private?

Completely. Everything you type stays in your browser — nothing is uploaded to any server, so commands, keys and data never leave your machine.

Do these tools touch my servers?

No. OpsForge tools are pure calculators and generators that run in your browser — they never connect to your infrastructure. You copy the result and apply it yourself.

Is the chmod calculator accurate for all systems?

Yes — octal permission notation is a POSIX standard, so the results apply identically on Linux, macOS and BSD.

Will more DevOps tools be added?

Yes — Dockerfile, docker-compose, nginx and CI config generators are on the roadmap. Everything will stay free and client-side.
