csv-to-sql

csv-to-sql is a skill for Claude Code, Codex from DavidROliverBA/ArchitectKB. It costs 9 tokens per session (1,602 once invoked), scanned A, original, MIT.

A converter that turns comma-separated value (CSV) files into SQLite databases. SQLite is a small database stored in a file that can be queried with SQL.

In plain words
What is it for?
Use it to import CSV data, skip metadata rows, create full-text search indexes, choose database and table names, and query the converted data.
Why use it?
Large CSV files can be awkward for a coding agent to read or search directly. A database makes it easier to filter rows, calculate totals, group results, and search long text.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

csv-to-sql scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 233 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/csv-to-sql

Convert CSV files into SQLite databases stored in .data/ for efficient querying by Claude Code.

Why SQLite? Large CSV data converted to markdown tables creates files too large for Claude Code to read efficiently. SQLite enables:

  • Direct SQL queries via sqlite3 CLI
  • Aggregations (AVG, COUNT, SUM, GROUP BY)
  • Full-text search on long content
  • Filtered retrieval (WHERE clauses)
  • JSON or markdown output formats

Usage

/csv-to-sql <csv-path>
/csv-to-sql Inbox/data.csv
/csv-to-sql Inbox/rfi.csv --start-row 14 --fts
/csv-to-sql Inbox/survey.csv --db-name survey-2026.db --table responses

Instructions

Phase 1: CSV Analysis

  1. Verify the CSV file exists at the specified path
  2. Run with --dry-run to preview schema:
    node scripts/csv-to-sqlite.js "<csv-path>" --dry-run --verbose
    
  3. Review the output to identify:
    • Column names and inferred types
    • Which columns will be indexed
    • If --start-row is needed to skip metadata

Phase 2: Database Creation

Run the conversion:

node scripts/csv-to-sqlite.js "<csv-path>" --start-row <n> --fts --verbose

Script Options:

Option Description
--db-name <n> Custom database filename (default: from CSV name)
--table <name> Table name (default: 'data')
--start-row <n> Skip first N rows (0-indexed, for metadata)
--fts Create full-text search index on long text cols
--dry-run Preview schema without creating database
--verbose Show detailed progress and schema

Phase 3: Verify and Query

After creation, test the database:

# Show table structure
sqlite3 .data/<db-name>.db ".schema"

# Preview data
sqlite3 .data/<db-name>.db -markdown -header "SELECT * FROM data LIMIT 5;"

# Count rows
sqlite3 .data/<db-name>.db "SELECT COUNT(*) FROM data;"

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
