# Format Unstructured Data into Copy-Paste Tables (AI Skill)

## Overview
Manually copying and pasting names, dates, amounts, and notes from 50 different emails or receipt PDFs into Excel or Google Sheets is tedious, error-prone manual labor.

The **Unstructured-to-Tabular ETL Protocol** transforms raw, chaotic text dumps into clean, standardized, copy-pasteable **TSV (Tab-Separated Values)** or **Markdown tables** in seconds.

## Master Data Formatting Prompt Templates

### Pattern 1: The Direct 1-Click Excel TSV Converter
Outputs text separated by tabs (`\t`), allowing you to copy the block and hit `Ctrl + V` directly into Excel or Google Sheets with zero import wizard hassle:

```markdown
Here is messy unstructured text:
[PASTE MESSY DATA]

Task:
Extract and normalize this into a TSV (Tab-Separated Values) code block with these exact columns:
1. `Date (YYYY-MM-DD)`
2. `Vendor / Person`
3. `Category (Design / Development / Marketing / Operations)`
4. `Amount (USD Number Only)`
5. `Status (Paid / Pending)`

Rules:
- Output ONLY the raw TSV code block.
- Format numbers cleanly (no `$` signs or commas in the number column so math formulas work in Excel).
```

### Pattern 2: The Customer Feedback Categorization Matrix

```markdown
Convert these customer feedback snippets into a Markdown table:
[PASTE CUSTOMER REVIEWS]

Columns:
| Customer ID | Sentiment (Positive/Neutral/Negative) | Primary Feature Mentioned | Core Friction Point | Actionable Recommendation |
```

## 3 Secrets for Flawless Spreadsheet Pasting
1. **Request TSV over CSV**: When pasting into Google Sheets, copying TSV from a markdown code block pastes instantly across cells without triggering comma-split bugs in addresses or notes.
2. **Enforce ISO Dates (`YYYY-MM-DD`)**: Prevents US/UK date format confusion (`05/06` vs `06/05`).
3. **Strip currency symbols from numeric columns**: Keeps numbers formatted as pure digits (`120.00` instead of `$120.00`) so spreadsheet `=SUM()` formulas work instantly.
