CSV Toolkit

Command-line CSV manipulation — view, filter, sort, select, convert, stats, dedup, and merge. Pure Python, no dependencies.

Quick Start

# View as formatted table
python3 scripts/csv_toolkit.py view data.csv
python3 scripts/csv_toolkit.py view data.csv --head 10

# Filter rows
python3 scripts/csv_toolkit.py filter data.csv -w 'age>30' 'city==Chicago'

# Sort
python3 scripts/csv_toolkit.py sort data.csv --by salary --desc

# Select columns
python3 scripts/csv_toolkit.py select data.csv -c "name,email,salary"

# Convert to JSON
python3 scripts/csv_toolkit.py to-json data.csv -o data.json

# Convert JSON back to CSV
python3 scripts/csv_toolkit.py from-json data.json -o data.csv

# Column statistics
python3 scripts/csv_toolkit.py stats data.csv -c "age,salary"

# Remove duplicates
python3 scripts/csv_toolkit.py dedup data.csv -o clean.csv

# Merge files
python3 scripts/csv_toolkit.py merge file1.csv file2.csv -o combined.csv

Commands

Command Description
view Display CSV as a formatted table. Use --head N / --tail N to limit rows.
filter Filter rows with -w conditions: col>val, col==val, col!=val, col\x3C=val. Multiple conditions = AND.
sort Sort by column with --by col. Add --desc for descending. Numeric-aware.
select Pick columns with -c "col1,col2".
to-json Convert CSV to JSON array of objects. Auto-detects numbers.
from-json Convert a JSON array of objects to CSV.
stats Column statistics: count, unique values, min/max/mean/median for numeric columns.
dedup Remove duplicate rows.
merge Concatenate multiple CSV files (same headers).

Global Options

Flag Description
-d, --delimiter Field delimiter (default: ,). Use -d ' ' for TSV.
--encoding File encoding (default: utf-8).
-o, --output Write result to file instead of stdout.
Usage Guidance
This appears to be a straightforward local CSV toolkit that operates on files you supply. Before installing or running it: (1) Inspect the remainder of scripts/csv_toolkit.py (the provided excerpt was truncated) to confirm there are no network calls, subprocess.exec/OS.exec usage, or code that reads unexpected system paths. (2) Run the tool in a sandbox or on non-sensitive sample files first. (3) Be cautious when opening CSV outputs in spreadsheet software (Excel/Sheets) because malicious CSV cells starting with =,+,- or @ can trigger formula execution in spreadsheet apps; sanitize if you plan to open outputs in such apps. If you want, provide the full script (untruncated) and I can re-check and raise confidence to high.
Capability Analysis
Type: OpenClaw Skill Name: csv-toolkit Version: 1.0.0 The csv-toolkit skill is a standard utility for manipulating CSV files, providing features like filtering, sorting, and format conversion. The Python script (scripts/csv_toolkit.py) uses only standard libraries and contains no evidence of malicious intent, data exfiltration, or unauthorized execution; its behavior is entirely consistent with its documented purpose in SKILL.md.
Capability Assessment
Purpose & Capability
Name/description match the SKILL.md and the included script: view, filter, sort, select, convert, stats, dedup, merge. The required resources (none) are proportionate to the stated purpose.
Instruction Scope
SKILL.md instructs the agent to run the local Python script against user-supplied files and standard CLI flags. The instructions only read/write files provided via arguments and do not direct data to external endpoints, request additional environment variables, or instruct the agent to read unrelated system files.
Install Mechanism
No install spec — instruction-only with a shipped Python script. There are no downloads, package installs, or extraction steps that would write or execute remote code.
Credentials
The skill requests no environment variables, credentials, or config paths. The code shown uses only Python standard library modules and reads/writes only files passed on the command line.
Persistence & Privilege
The skill is not always-enabled and does not request persistent privileges or modify other skills or system-wide agent settings. It runs only when invoked.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install csv-toolkit
  3. After installation, invoke the skill by name or use /csv-toolkit
  4. Provide required inputs per the skill's parameter spec and get structured output
