A converter that turns CSV files into page notes containing Markdown tables. CSV is a text format for rows and columns, while Markdown is a plain-text format commonly used for formatted notes.

Use it to import spreadsheets or exports into notes, detect commas, semicolons, or tabs, align numeric columns, escape special characters, and split long rows into separate notes.

It preserves complete cell contents instead of shortening long values. It also handles different separators, quoted fields, multi-line text, and Markdown characters.

Install

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00014	$0.01639
Opus 5	$0.00007	$0.00820
Sonnet 5	$0.00003	$0.00328
Haiku 4.5	$0.00001	$0.00164

Security

Grade A, and why

csv-to-page 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 10d 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.

The opening of the file, as written. The whole thing — 234 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/csv-to-page

Convert CSV files into Page notes with properly formatted markdown tables.

Key Feature: No content truncation by default - full cell content is preserved regardless of length (PapaParse has no cell size limits; V8 engine supports strings up to 512MB).

Features:

RFC 4180 compliant parsing via PapaParse
No truncation - full cell content preserved (up to 512MB per cell)
Auto-detects delimiter (comma, semicolon, tab)
Handles quoted fields, multi-line content, embedded commas
Escapes markdown special characters (pipes, backslashes)
Auto-detects numeric columns for right-alignment
Split mode - create individual notes for rows with long content

Usage

/csv-to-page <csv-path>
/csv-to-page Inbox/data.csv
/csv-to-page Inbox/rfi.csv --split --split-folder "RFI-Responses"
/csv-to-page Inbox/data.csv --truncate 150  # Optional truncation

Instructions

Phase 1: CSV Analysis

Verify the CSV file exists at the specified path

Run analysis to understand structure:

node scripts/csv-to-markdown.js "<csv-path>" --output-json

Review the output to identify:
- Total rows and columns
- Empty rows (common in Excel exports)
- Maximum cell length (determines if split mode recommended)
- Whether there are metadata/instruction rows before actual data

Phase 2: Choose Conversion Mode

Based on the analysis, recommend a mode to the user:

Use AskUserQuestion:

Question: "How should the CSV be processed?"
Header: "CSV Mode"
Options:
  1. "Full table (Recommended for simple data)"
     Description: "Single markdown table with all content preserved"
  2. "Split mode (Recommended for long content)"
     Description: "Individual note per row - best for RFIs, surveys, responses"
  3. "Truncated summary"
     Description: "Compact table with truncated cells for overview"

Recommendations:

Full table: For CSVs with cells under 500 characters
Split mode: For RFI responses, surveys, or any CSV with cells over 1000 characters
Truncated: Only when user specifically needs a compact summary view

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.
