Parse, query, transform, validate, and convert JSON and YAML data using jq and fy (fast-yaml). Use when the user asks to filter JSON arrays, extract nested fields, reshape data structures, convert between JSON and YAML formats, validate or lint YAML files, pretty-print or minify JSON, format YAML, or perform complex data transformations on structured 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

# JSON & YAML Processing with jq and fy

## Quick Reference

| Action | Command |
|--------|---------|
| Pretty-print JSON | `jq . file.json` |
| Minify JSON | `jq -c . file.json` |
| Extract field | `jq '.name' file.json` |
| Extract raw string | `jq -r '.name' file.json` |
| Validate YAML | `fy parse file.yaml` |
| Format YAML | `fy format -i file.yaml` |
| Lint YAML | `fy lint file.yaml` |
| YAML to JSON | `fy convert json file.yaml` |
| JSON to YAML | `fy convert yaml file.json` |
| Validate JSON | `jq empty file.json` |

## jq Basics

### Identity and Field Access

```bash
# Identity (pass-through, pretty-print)
cat data.json | jq .

# Access nested field
jq '.user.address.city' data.json

# Access array element
jq '.[0]' data.json
jq '.items[2]' data.json

# Access multiple fields (comma operator)
jq '.name, .age' data.json

# Optional field access (no error if missing)
jq '.missing?' data.json
```

### String Interpolation

```bash
# Build strings from fields
jq -r '"Name: \(.name), Age: \(.age)"' data.json

# Use in filters
jq -r '.[] | "User \(.id): \(.email)"' users.json
```

### Raw Output

```bash
# -r removes quotes from string output
jq -r '.name' data.json

How to install

The exact contents, by fingerprint
mdr add bug-ops/zeph/json-yaml@sha256:ebf758308b3d7b58

The line at the top of this page pins the label v1.0, 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.
