Cleans, validates, and transforms CSV files for analysis. Use when user says "clean this CSV", "fix my data", "prepare this spreadsheet for analysis", "validate this dataset", or uploads a .csv file that needs processing.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# CSV Data Pipeline
## Instructions
### Step 1: Inspect the Data
When the user provides a CSV file:
1. Read the first 10 rows to understand structure
2. Count total rows and columns
3. Identify column types (text, number, date, boolean, email, URL)
4. Report findings to the user:
```
"Your file has {rows} rows and {cols} columns.
Here's what I found:
- {col_name}: {type} ({null_count} missing values)
- ...
{issues_count} potential issues detected."
```
### Step 2: Identify Issues
Check for these common problems:
| Issue | Detection | Auto-fix? |
|-------|-----------|-----------|
| Missing values | Null/empty cells | Ask user |
| Duplicate rows | Exact row matches | Yes |
| Inconsistent dates | Multiple formats in same column | Yes — standardize to YYYY-MM-DD |
| Leading/trailing whitespace | Strip and compare | Yes |
| Mixed case in categories | "Active" vs "active" vs "ACTIVE" | Yes — normalize to lowercase |
| Outliers | Values > 3 standard deviations from mean | Flag, don't auto-fix |
Present issues to the user and ask which to fix.
### Step 3: Apply Fixes
For each approved fix:
```bash
python scripts/validate_csv.py --input {filename} --checks all
```
…Read the whole file at its exact version.
How to install
mdr add earlyaidopters/gumroad-resources/csv-data-pipeline@sha256:d2e3ccef234fec47The line at the top of this page pins the label git:20260810.9572c5c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
