Make_data

A Rust command-line tool to generate random (artificial) data. Data is saved as a CSV file. You can specify the number of rows, the types of columns (integer, float, word, name, phone), and the output file name. This is useful for generating mock data for testing, demos, or data science projects.

Features

• Generate random integers, floats, words, names, and phone numbers
• Specify the number of rows and column types via command line
• Output to a CSV file with customizable filename

Setup

1. Install Rust (if not already installed):

   curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

2. Clone or download this repository and navigate to the project directory:

   cd /path/to/make_data

3. Build the project:

   cargo build --release

Usage Examples

Generate a CSV file with 100 rows, where the first column is an integer, the second is a float, the third is a random word, the fourth is a name, and the fifth is a phone number:

cargo run --release -- --rows 100 --columns int,float,word,name,phone --output mydata.csv

This will create mydata.csv in the project directory.

All columns as random numbers

Generate a CSV file with 50 rows and 5 columns, all integers:

cargo run --release -- --rows 50 --columns int,int,int,int,int --output all_ints.csv

Generate a CSV file with 50 rows and 5 columns, all floats:

cargo run --release -- --rows 50 --columns float,float,float,float,float --output all_floats.csv

Dependencies

• clap for command-line argument parsing
• rand for random number generation
• csv for CSV writing
• fake for generating names, phone numbers, and words
