Populating Investment Banking Pitch Deck Templates

Reference Files

Read all reference files at task start before beginning any work. These contain critical patterns and anti-patterns that will affect your approach. Do not wait until you encounter issues.

├─ Editing existing populated slides?
│  └─→ Extract current content, modify, revalidate
│
└─ Fixing formatting issues on existing slides?
   └─→ See "Common Failures" table, apply targeted fixes

⚠️ Critical Rendering Limitation

LibreOffice is used for validation but DOES NOT render PowerPoint files accurately. It will mangle fonts, gradients, shape positions, text wrapping, and some table formatting.

What this means: A slide that passes visual validation in LibreOffice may still have issues in Microsoft PowerPoint. The validation loop catches structural issues (missing content, broken tables, placeholder formatting retained) but cannot catch font substitution, subtle alignment shifts, or gradient problems.

Required action: Always include this statement when delivering output:

"This file was validated using LibreOffice. Please review in Microsoft PowerPoint before distribution, as rendering differences may exist."

Template Population Workflow

Copy and track progress:

Pitch Deck Progress:
- [ ] Phase 1: Extract and validate source data
- [ ] Phase 2: Map content to template sections
- [ ] Phase 3: Populate slides with proper formatting
- [ ] Phase 4: Validate → Fix → Repeat until clean
- [ ] Phase 5: Final verification

Phase 1: Data Extraction

1. Create backup of original template before any modifications — copy to [filename]_backup.pptx. Direct XML editing or unexpected errors can corrupt files.
2. Identify all source materials (Excel, CSV, PDF reports, Word documents, databases, web sources)
3. Extract relevant data points from each source
4. Validate all numbers against original sources
5. Standardize units and currency (convert all figures to the primary unit/currency used in the template)
6. Note any calculations that need verification → see calculation-standards.md for formulas

Phase 2: Content Mapping

1. Open and visually review the template — understand its structure, style, and existing content before modifying
2. Analyze template structure — identify all placeholder areas and content boxes
3. Map source data to corresponding template sections → see slide-templates.md for mapping guidance
4. Identify placeholder guidance boxes (colored instruction boxes from task creator)
5. Note any data gaps or mismatches → see slide-templates.md for resolution

Phase 3: Template Population

1. Remove or reformat placeholder boxes — colored instruction boxes show WHAT to create, not HOW to format. Delete them and create properly formatted content in their place. See Critical Anti-Patterns.
2. Populate each section with mapped content (focus on content first)
3. Then apply formatting to match template style → see formatting-standards.md
4. Create tables as actual table objects (NEVER use pipe/tab-separated text) → see xml-reference.md
5. Create arrows/shapes as PowerPoint objects → see xml-reference.md
6. Insert company logo if provided in task files; if not available, flag to user: "[LOGO NOT PROVIDED - please supply company logo]"

Phase 4: Validate → Fix → Repeat

This is a feedback loop. Repeat until all checks pass OR escalation is triggered.

# Convert to images for visual validation

Validation checklist (check each slide image):

• Text readable against background?
• Tables are actual objects (columns aligned, NOT pipe/tab-separated text)?
• Charts/tables fill designated areas?
• Bullet formatting consistent within sections?
• Font sizes match across same-level boxes?
• No content beyond slide boundaries?
• No placeholder formatting retained (no large colored boxes with data dumped in)?
• No text-based "tables" (no | or tab separators creating fake columns)?
• Cross-slide consistency: Same metrics/figures identical across all slides where they appear?

Fix cycle protocol:

After 3 cycles, if issues remain:

1. List each unresolved issue with slide number and description
2. Explain what was attempted
3. Deliver the file with explicit disclaimer: "The following issues could not be resolved automatically: [list]. Manual review required."

Do not continue cycling indefinitely. Some issues (font rendering, complex shape alignment) may require manual intervention in PowerPoint.

Phase 5: Final Verification

Run through the Final Quality Checklist before delivering.

Quick Reference Tables

Bullet Symbols

Slide Hierarchy Levels (Typical)

These are typical ranges—adjust based on template specifications:

Font Consistency Matching

Boxes at the same hierarchy level MUST use identical font sizes:

Rounding for Presentation

These are typical conventions — adjust based on the magnitude of values and template style:

Principle: Rounding should not materially change the figure. For smaller values, use finer precision.

Text Density Rules

• Max 6-7 bullets per content box
• Max 2 lines per bullet point
• Parenthetical examples: same line or indented below
• No orphan words (single word on new line)

Alignment Principles

Vertically stacked boxes must have identical:

• Left margin position, bullet indentation, text start position, box width

Horizontally adjacent boxes must have identical:

• Top position, height (where possible), internal padding

Multi-Slide Consistency

When the same data appears on multiple slides:

• Use identical figures, formatting, and terminology
• If a metric is updated on one slide, update all occurrences
• Cross-reference during validation to catch mismatches

MUST Requirements

These requirements are non-negotiable regardless of template:

Critical Anti-Patterns: NEVER DO THESE

These failures occur when placeholder formatting is mistaken for output formatting. Recognizing these patterns is essential.

Anti-Pattern 1: Populating Data INTO Placeholder Boxes

What happens: Template has colored instruction boxes (yellow, orange, etc.) with guidance text. Model replaces the guidance text with actual data BUT KEEPS THE COLORED BOX.

Why it's wrong: The colored box IS the placeholder. It tells you what content goes there. The output should have different formatting — typically dark text on white/light background, or properly styled shapes.

Recognition test: If your populated slide has large colored rectangles filled with data text, you have copied the placeholder format instead of replacing it.

Critical distinction — two types of "placeholders":

If uncertain: check if the shape exists on an empty slide from the same template. Layout placeholders persist; instruction boxes are regular shapes.

Anti-Pattern 2: Text-Based "Tables"

What happens: Model creates table-like content using separator characters (|, tabs, spaces) instead of actual table objects.

Why it's wrong: This is NOT a table. Columns will never align properly, it cannot be formatted consistently, and it looks unprofessional.

Recognition test: If you're typing | characters or relying on spaces/tabs to create columns, you're creating text, not a table.

MUST verify: After creating any table, verify it is an actual table object. See xml-reference.md for verification methods.

Anti-Pattern 3: Inheriting Placeholder Contrast

What happens: Placeholder uses light text on colored background (e.g., white on yellow). Model populates data but keeps this color scheme, resulting in hard-to-read output.

Why it's wrong: Placeholder colors are deliberately distinct to signal "replace me." Production slides typically use dark text on light backgrounds for body content.

Recognition test: If your populated content has light/white text on bright colored backgrounds in body areas (not headers), you've inherited placeholder formatting.

Correct approach: Apply production formatting — typically dark text (#000000 or #333333) on white or light backgrounds for body content. Headers and accent areas may use brand colors.

Summary: Placeholder vs. Production

The placeholder tells you WHAT to create, not HOW to format it.

Common Failures

For detailed explanations of the most critical failures, see Critical Anti-Patterns above.

Error Handling

If PDF/image conversion fails:

1. Check LibreOffice is installed: which soffice
2. Try alternative: libreoffice --headless --convert-to pdf presentation.pptx
3. If still failing, open in PowerPoint/LibreOffice manually and export

If source data has inconsistencies or conflicts:

1. Priority order: Use data explicitly provided in the task files first
2. If using data from other sources (web search, external documents), flag this to the user
3. Document any discrepancies explicitly
4. Add footnote explaining data source choice

If calculations don't match source projections:

1. Show your calculation methodology
2. Note the discrepancy and possible causes (different base year, methodology)
3. Present both values if material difference
4. Flag to user for resolution

Table Structure Guidelines

When creating tables (MUST be actual table objects):

Column Alignment:

• Text columns: Left-aligned (header and content)
• Numeric columns: Right-aligned or center-aligned (header matches content)

Header Row:

• Bold text
• Shaded background (template's brand color)
• White or contrasting text

Consensus/Total Row:

• Bold text
• Separator line above
• Distinct background shading

Width: Fill designated section width completely.

For XML implementation, see xml-reference.md.

Footnote Format

Format:

Sources: [Source 1] (Year), [Source 2] (Year).
Notes: (1) [First note]; (2) [Second note].

Example:

Sources: Grand View Research (2024), Mordor Intelligence (2024), Markets and Markets (2023).
Notes: (1) Excludes hardware revenue; (2) Includes both B2B and B2C segments.

All superscript numbers (¹, ², ³) in slide body MUST have corresponding Notes entries.

Logo Placement

• Use logo file provided in task materials
• If no logo provided, flag to user: "[LOGO NOT PROVIDED - please supply company logo]"
• Position: typically top-right, consistent size across slides, must not overlap content

Data Requirements by Slide Type

For detailed data requirements, formatting principles, and example column headers for each slide type, see slide-templates.md.

Common slide types covered: Market Definition, Market Sizing/TAM, Competitive Landscape, Financial Summary, Transaction Comparables.
