Excel, minus the busywork.

Inavolus Tools takes the spreadsheet nobody wants to touch — duplicates, stray spaces, mixed dates, currency junk — and makes it clean and trustworthy in one click. Then an AI analyst sits beside your data to answer questions, write formulas, and label columns. No syntax to memorize. Nothing to break.

🔒 Cleaning runs 100% on your device — your data never leaves

See it work — drop a messy CSV

This demo runs entirely in your browser. Nothing is uploaded. (The Excel add-in does the same, on your selection.)

Built for the person who inherited the spreadsheet

A dozen one-click tools that fix the boring stuff — free and unlimited, right on your device. The AI analyst turns an afternoon of grunt work into a few seconds.

🧹

One-click cleanup

Trim spaces, drop empty rows/columns, remove duplicates, tidy headers — in one click.

📅

Smart date & number fixing

Auto-detects mixed date formats → YYYY-MM-DD and strips $ , % from numbers.

💬

Ask your data

"Which region grew fastest?" — get answers from the selected range in plain English.

Generate formulas

Describe what you want in plain English; Inavolus writes the Excel formula and drops it into the active cell.

🏷️

Categorize & extract

Label a column into your categories, or pull a field out of messy text — into a new column.

🔠

Change case & clean text

One click to UPPER, lower, Title or Sentence case — and strip accents, symbols, and double spaces.

✂️

Split & merge columns

Text-to-columns by any delimiter, split full names into first/last, or combine fields into one.

🔎

Find, replace & extract

Bulk find & replace, pull emails/URLs/numbers into a new column, and fill blank cells down.

🔁

Excel today, Sheets next

Built on one shared engine, so Google Sheets support is an adapter — not a rewrite.

Privacy by architecture, not by promise

Most "AI for spreadsheets" tools ship your data to a SaaS black box. Inavolus Tools is built so your data path is something you can actually see — and, when self-hosted, control.

Cleaning
Runs on your device, inside the task pane. Spreadsheet content is never transmitted.
AI requests
Only the cells you select go to your self-hosted proxy, then to Anthropic — which does not train on API data.
What we store
No spreadsheet content. Only an anonymous usage count and your license key.

FAQ

Does my spreadsheet data get uploaded?

No — cleaning runs entirely on your device. Only the AI features send the cells you selected, and only to the self-hosted proxy and Anthropic. See the Privacy Policy.

Do I need an API key?

Cleaning needs nothing. AI features use the operator's proxy, which holds the key server-side — it never reaches the add-in.

Will it work in Google Sheets?

Excel ships first. The cleaning/AI engine is platform-agnostic, so Sheets support is a thin adapter on the same core.

Can I cancel anytime?

Yes. Pro and Max are month-to-month subscriptions — cancel anytime and access continues to the end of the current billing period.
