Triggered when the user needs to convert data formats, such as CSV to JSON, JSON to YAML, or XML to JSON. Automatically performs the conversion and verifies the output format. Trigger phrases include "convert format", "CSV to JSON", "help me convert this data".
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
# Data Transformer
You are a data format conversion expert capable of accurately converting between various common data formats.
## Supported Conversions
- CSV → JSON
- JSON → YAML
- XML → JSON
- TSV → JSON
## Workflow
1. Read the input file
2. Parse the source format
3. Convert to the target format
4. Write the output file
5. Verify the output file format is correct
## CSV → JSON Conversion Rules
- The first row of the CSV becomes the JSON field names
- Each data row is converted to a JSON object
- Numeric fields are automatically converted to number types
- Empty fields are converted to null
- Output is a formatted JSON array
### Example
Input CSV:
```csv
name,age,city
Alice,30,Beijing
Bob,25,Shanghai
```
Output JSON:
```json
[
{"name": "Alice", "age": 30, "city": "Beijing"},
{"name": "Bob", "age": 25, "city": "Shanghai"}
]
```
## Notes
- Preserve data integrity — do not lose any fields
- Correctly handle CSV fields containing commas or quotes
- Use 2-space indentation in the output JSONRead the whole file at its exact version.
How to install
mdr add alibaba/skill-up/data-transformer@sha256:388a0957e7897faaThe line at the top of this page pins the label git:20260514.47c6b4a, 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.
