What is the Data Engine suite in DeckMedic?

The Data Engine is Station 8 of DeckMedic — the final station — with two tools for cleaning financial and analyst PowerPoint decks: Decimal Normalizer scans every table cell and applies consistent decimal precision across all numbers; Ghost Box Buster finds and physically deletes empty text box shapes left by AI generators and template editors.

Why do AI-generated financial decks have inconsistent decimal places?

AI presentation tools like Copilot and Gamma generate table data from language models that produce numbers with inconsistent precision — sometimes 0 decimals ('$10'), sometimes 2 ('$10.00'), sometimes 3 ('$10.001'). When combined with data copied from Excel, Bloomberg, or FactSet, the mixed formatting violates basic IB formatting standards. The Decimal Normalizer standardizes every numeric table cell to your chosen precision in one pass.

The Problem

✗ AI tools generate financial tables with mixed decimal precision — Bloomberg at 2dp, LLM at 1dp, Excel paste at 3dp, all in the same table
✗ AI generators leave invisible empty text boxes on slides — clicking activates them accidentally during live client presentations
✗ CIM documents and pitch books uploaded to cloud PPTX tools expose deal values and client identifiers to remote servers

The Fix

✓ Decimal Normalizer enforces your chosen precision (0–3 decimal places) across every table cell in one pass — with a full cell-by-cell audit log
✓ Ghost Box Buster deletes every empty p:sp shape the AI left behind — no more click-through accidents in client workshops
✓ The Data Engine runs entirely in browser memory via JSZip Web Workers — no upload, no server, SOX and GDPR safe by design

Tool 21

Ghost Box Buster

Finds and physically deletes every empty or whitespace-only text box shape in your deck — the invisible placeholders left behind by AI generators. Stop the accidental cursor blink mid-presentation. Shows a per-slide removal report.

Who uses the Data Engine

🏦

Investment Banking Analysts

MD review is brutal. "Why does this column say '$8.5' and this one '$8.50' and this one '$8.500'?" One pass of Decimal Normalizer before you send to review — and that comment disappears. Every number formatted identically.

📈

Equity Research

Research reports contain dense financial tables sourced from models, terminals, and AI tools. Decimal Normalizer ensures all EPS, revenue, and margin figures display at consistent precision — maintaining credibility with buy-side readers.

💼

Strategy Consultants

AI-generated strategy decks are fast to create but full of ghost boxes from unfilled template regions. Ghost Box Buster cleans up before the deck is used in a client workshop — no more accidental cursor activation during a live facilitation.

The Analyst QA Workflow

1

Run Ghost Box Buster first

Drop your AI deck. All empty placeholder shapes are physically deleted. Download the _ghost_boxes_removed.pptx. This comes first because it changes the shape structure — run it before any final review.
2

Run Decimal Normalizer

Drop the cleaned file. Choose your target precision (IB standard: 1 decimal for multiples, 2 for per-share values, 0 for headcount). All table numbers normalized. Download the _decimals_fixed.pptx.
3

Review the audit logs

Both tools produce detailed reports: Ghost Box Buster shows per-slide shape counts; Decimal Normalizer shows every cell that changed with before/after values. Screenshot these logs before MD review.
4

Send to review

Your deck now has consistent number formatting across all tables and no invisible click targets. The two most flagged formatting issues in analyst decks — eliminated.

Frequently asked questions

What is the Data Engine suite?

Two tools for analyst PowerPoint decks: Decimal Normalizer standardizes all numeric table cell precision; Ghost Box Buster removes invisible empty text box shapes. Both run free, in-browser, with zero upload.

Why do AI financial decks have inconsistent decimal places?

Language models generate numbers with inconsistent precision — '$10', '$10.00', '$10.001'. Combined with data from Bloomberg or Excel, a single table can have six different precision levels. Decimal Normalizer fixes all of it in one pass.

Why do empty text boxes appear after editing an AI deck?

AI generators build slides from templates with many placeholder regions. When a placeholder isn't filled, the shape container remains in the XML with empty text. Deleting text in PowerPoint's editor leaves the shape — Ghost Box Buster physically removes the shape from the XML.

Do both tools work with confidential financial data?

Yes. Both tools process PPTX files entirely within the browser using Web Workers. No content, metadata, or numeric data is transmitted to any server. Suitable for CIM documents, pitch books, and any confidential financial presentation.
