# Excel Formula Generator

> Kenerate's Excel formula generator turns one plain-English sentence into an Excel formula, explained step by step, with any of 6 chat models. Say what the cell should do and which columns hold the data; Kenerate Agent writes the formula, says how it works, and can build an XLSX with the formulas already in place.

## Key facts
- Input: A plain-language description, plus your column layout or pasted data (up to 20,000 characters)
- Output: The formula and an explanation in the chat · optionally an XLSX with the formulas in place
- Live in the XLSX: SUM, SUMIF(S), SUMPRODUCT, AVERAGE(IF), COUNT, COUNTIF(S), IF, IFERROR, AND, OR, INDEX, MATCH, ROUND, TODAY and more
- Explained in chat only: XLOOKUP, IFS, TEXT, DATEDIF, UNIQUE, FILTER and other newer functions, to paste in yourself
- Workbook: Up to 10 sheets, typed columns, frozen header, filters and a totals row
- Chat models: Claude Opus 5.5 · Claude Fable 5.1 · GPT-6 Astra · GPT-6 Sol · GPT-6 Luna · Gemini 3.6 Flash
- Files you can attach: Images, video and audio only, so paste cells as text instead of uploading a sheet
- Access: Sign in with a verified email to send messages

## Steps
1. Open Kenerate Agent — Go to the chat and sign in. Sending a message needs an account with a verified email.
2. Describe the result you want — Say what the cell should work out and which columns hold the data. Paste a few sample rows if you can.
3. Get the formula and the why — The agent writes the formula, explains each part, and suggests a fix for common errors.
4. Paste it, or download a workbook — Copy the formula into your sheet, or ask for an XLSX built with the formulas already in place.

## In depth

### Which formula for which job
Most everyday spreadsheet questions fall into a handful of patterns. Name the pattern in your message and the agent picks the matching function.
- Add up with conditions: SUMIFS (several conditions) or SUMIF (one).
- Count with conditions: COUNTIFS or COUNTIF.
- Look something up in another table: XLOOKUP in current Excel, or INDEX with MATCH where it has to run everywhere.
- Decide between outcomes: IF for two, nested IF or IFS for several, IFERROR to catch errors.
- Work with dates: DATEDIF for whole years or months between dates, TODAY for the current date, TEXT to format a date.
- Pull out a list: UNIQUE for distinct values, FILTER for rows that match a condition.

### Formula in the chat, or formula in a file
In the chat, the agent can write any Excel or Google Sheets formula and explain it. When it builds an XLSX for you, only functions from a fixed, widely supported list go in as live formulas: SUM, SUMIF, SUMIFS, SUMPRODUCT, AVERAGE, AVERAGEIF, MIN, MAX, COUNT, COUNTA, COUNTIF, COUNTIFS, ROUND, ROUNDUP, ROUNDDOWN, IF, IFERROR, AND, OR, NOT, ABS, MEDIAN, PRODUCT, INDEX, MATCH, CONCATENATE, LEN, UPPER, LOWER, TODAY, YEAR, MONTH, DAY and SUBTOTAL. A formula using anything else, such as XLOOKUP or FILTER, is stored in the cell as text, so paste those in yourself.

### Fixing a formula that returns an error
Paste the formula, the error (#N/A, #VALUE!, #REF!, #DIV/0!) and a few sample rows. The usual causes are a lookup value stored as text in one table and a number in the other, ranges of different sizes in SUMIFS, a deleted column, or dividing by an empty cell. The agent names the likely cause and gives a corrected formula, often wrapped in IFERROR for a clean result.

### Newer functions need a newer Excel
XLOOKUP, UNIQUE and FILTER need a recent Excel (Microsoft 365 or Excel 2021 and later) or Google Sheets, and IFS needs Excel 2019 or later. If you share files with people on older versions, ask for INDEX/MATCH and nested IF instead; they work everywhere.

## FAQ
Q: What is an Excel formula generator?
A: An Excel formula generator turns a description of what you want into a formula. Instead of remembering argument order for SUMIFS or INDEX/MATCH, you write "total sales for North in March" and get =SUMIFS(D:D, B:B, "North", C:C, "March"). Kenerate Agent also explains each part, so you can adjust the formula yourself next time.

Q: How do I create an Excel formula with AI?
A: Open Kenerate Agent, describe what the cell should calculate and say which columns hold which data, for example "dates in A, amounts in C, rows 2 to 200". The agent writes the formula and explains it. Paste it into your sheet and copy it down. If it returns an error, paste the error and a few rows back into the chat and ask for a fix.

Q: Can it explain a formula I already have?
A: Yes. Paste the formula into the chat and ask what it does. The agent breaks it into parts, explains each function and range in plain words, and points out likely problems, such as a range that won't grow with new rows or a lookup that fails on text stored as numbers. It replies in the language you write in.

Q: Will the formulas work in Google Sheets?
A: Most will. SUMIFS, COUNTIFS, IF, INDEX/MATCH, TEXT, UNIQUE and FILTER exist in both Excel and Google Sheets, and Google Sheets also supports XLOOKUP. Say which app you use in your message so the agent picks functions that exist there and uses the right separators for your region if you mention it.

Q: Can it build a spreadsheet with the formulas already in it?
A: Yes. Ask for a workbook and the agent builds an XLSX with up to 10 sheets, typed columns and live formulas for every calculated cell, plus an optional totals row. The file carries widely supported functions such as SUMIFS, COUNTIFS, IF, IFERROR and INDEX/MATCH; newer ones such as XLOOKUP or FILTER are given in the chat for you to paste in.

Q: Can I upload my workbook so it sees my columns?
A: No, chat attachments are images, video and audio only. Copy the header row and a few sample rows from your sheet and paste them into the message (up to 20,000 characters). That gives the agent the column letters and data types it needs to write a formula that fits your sheet.

Q: Is it better than Copilot in Excel?
A: They suit different moments. Copilot in Excel works inside your open workbook and can add formula columns to it directly. Kenerate Agent works in a chat: it explains formulas in detail, builds a new workbook from scratch, and sits next to document, slide, image and video tools. If you already work all day in Excel with Copilot, that is the closer fit.
