Create a Presentation From Excel or a Spreadsheet
Upload your Excel (.xlsx / .xls) or CSV file and get a structured presentation built from it — no retyping rows of numbers into slides by hand. The part that matters with data is accuracy: Gixo reads figures from your spreadsheet and keeps that source attached to the generation and review path. Verify source-critical numbers before presenting.
The short answer
You have the numbers in a spreadsheet — a metrics export, a budget, a results table — and you need them in a deck. The slow way is retyping each figure into slides, where a single fat-fingered digit becomes a wrong number in front of an audience. AI can do the conversion, but only if it carries your actual figures across rather than approximating them.
Gixo reads your spreadsheet directly: Excel workbooks are parsed cell-by-cell, and CSVs are read as rows and columns. When sources are provided, Lumen keeps uploaded and pasted material authoritative and lets the user choose uploaded-only generation or allow web context. Lumen records generation-time source provenance and keeps citations and source review attached; it does not automatically verify every claim, so human review remains required.
The result is a structured, editable deck you can refine and export — built from your real data, not a plausible-looking version of it.
How to turn a spreadsheet into a deck
When you create a presentation, upload your Excel (.xlsx / .xls) or CSV file as a reference document (you can add a few related files too). Excel workbooks are read cell-by-cell; CSVs are read as their rows and columns.
Keep generation uploaded-only when the sheet must be the sole source, or allow web context while keeping the spreadsheet authoritative.
When source material does not support a specific fact, Lumen instructs generation to omit it or use neutral, non-numeric wording. Reviewers should verify source-critical claims before presenting. Compare source-critical figures with the workbook before presenting.
Tweak the deck in Lumen, then export it using the hybrid PowerPoint path. PowerPoint export is hybrid by design: stable layouts become editable text and shapes, complex slides preserve fidelity as images, and the file opens cleanly in PowerPoint.
Why this matters more for data than for anything else
A deck built from a topic can be vague and still be useful. A deck built from a spreadsheet can't — its whole reason to exist is the numbers, and a wrong one undermines the entire thing. That's why the conversion has to be faithful: the figure on the slide should be the figure in your cell, full stop.
Source provenance makes the review path visible, but it is not automatic claim verification. For a results review, board update, or investor deck, compare source-critical numbers with the workbook and correct the working deck before handoff.
