File Convert

File format conversion between CSV, JSON, and Markdown. Use when the user needs to convert a CSV to JSON, convert JSON to CSV, turn a spreadsheet export into JSON, flatten JSON into a CSV, parse a Markdown file's frontmatter into JSON, generate a Markdown file with YAML frontmatter from JSON, or convert data between these formats. Triggers include "convert CSV to JSON", "csv to json", "ubah csv ke json", "convert JSON to CSV", "json to csv", "flatten JSON to CSV", "parse frontmatter", "markdown to json", "md to json", "json to markdown", "extract frontmatter", "convert this file", "konversi file", "change file format", or any task requiring CSV/JSON/Markdown interconversion.

File contents

file-convert

Convert data between CSV, JSON, and Markdown (YAML frontmatter + body).

Run CLIs from this skill's directory (the folder that contains this SKILL.md): uv run scripts/<name>.py. Do not prefix skills/file-convert/.

Available Scripts

Unified CLI

uv run scripts/convert.py data.csv --from csv --to json

--from/--to accept csv, json, md. Supported directions: csv→json, json→csv, md→json, json→md. Reads - for stdin.

CSV → JSON

uv run scripts/csv_to_json.py data.csv          # infers int/float/bool/null
uv run scripts/csv_to_json.py data.csv --no-infer   # keep strings

Streams rows via csv.DictReader; emits a JSON array. --delimiter to change separator.

JSON → CSV

uv run scripts/json_to_csv.py data.json         # flattens nested keys (a.b.c)
uv run scripts/json_to_csv.py data.json --no-flatten  # nested → JSON strings

Accepts a JSON array of objects (or a single object). Header is the union of keys.

Markdown → JSON

uv run scripts/md_to_json.py post.md

Splits YAML frontmatter (between --- fences) from the body. Emits {"frontmatter": {...}, "body": "..."}.

JSON → Markdown

uv run scripts/json_to_md.py post.json

Reads {"frontmatter": {...}, "body": "..."} and writes a Markdown doc with a YAML frontmatter block followed by the body.

Round-trip

csv → json → csv and json → md → json preserve data when flattening is off or keys have no dots. unflatten() cannot rebuild JSON arrays (list indices become dict keys).

Output & Exit Codes

Converters write their result to stdout; diagnostics to stderr.
Exit 0 success, 1 error, 2 file not found.

Notes

CSV↔JSON is standard-library only. Markdown conversion pulls in PyYAML via a PEP 723 inline dependency (correct YAML beats a hand-rolled parser).
