Lumen
AI data insights platform that turns your Excel sheets into conversational analysis.
About Lumen
Lumen is the AI data platform that turns your spreadsheets into conversational analysis. Upload your Excel or CSV files and it builds an interactive data workspace where you can ask questions, generate charts, and share dashboards.
It is designed for people who do not code: natural language queries produce tables, charts, and insights automatically, and everything updates when your data changes.
For teams that want self-serve analytics without hiring a data team, Lumen is the most approachable option in the category.

Lumen: strengths and trade-offs
Our own read on the product — written from the vendor’s documentation and our use of it, not from a vendor brief.
What it does well
- Conversational analysis on Excel files without learning a BI tool or writing formulas.
- Explains the steps it took, which makes the numbers easier to trust than a black-box result.
- Fast for exploratory questions on a dataset you already have.
Where it falls short
- Struggles with messy or inconsistently structured spreadsheets.
- Not a replacement for a proper BI stack once reporting becomes recurring.
- Confidentiality terms need checking before uploading sensitive sheets.
Who should skip Lumen
- Production dashboards and recurring reporting.
- Highly regulated datasets.
