📝📊 Convert your CSV files into Markdown tables.

csvtomd: markdown tables made easy

Convert your CSV files into Markdown tables.

Tables Generator is a fantastic web tool for converting tabular data into all sorts of table layouts. I like how it lets me import CSV files, but I need the ability to convert many CSV files in batch for a docset on which I'm working.

I built csvtomd to convert one or more CSV files into nicely-padded Markdown tables. Now you can build your tables in Excel and convert them for use in GitHub Markdown files without having to construct them by hand.

Installation

This is a Python 3 script, so use pip3 to install:

pip3 install csvtomd

After this, run csvtomd --help from your terminal to verify it's installed properly.

Usage

csvtomd MY_SPREADSHEET.csv generates a Markdown table from MY_SPREADSHEET.csv.

csvtomd SHEET1.csv SHEET2.csv SHEET3.csv generates three Markdown tables from the input files and displays them alongside the input filename.

csvtomd or csvtomd - generates a Markdown table from standard input. You can type CSV data or pipe a file in.

Example Input

File: thrones.csv

First Name,Last Name,Location,Allegiance
Mance,Rayder,North of the Wall,Wildlings
Margaery,Tyrell,The Reach,House Tyrell
Danerys,Targaryen,Meereen,House Targaryen
Tyrion,Lannister,King's Landing,House Lannister

Example Markdown Table

Command: csvtomd thrones.csv

First Name	Last Name	Location	Allegiance
Mance	Rayder	North of the Wall	Wildlings
