csv_stacker

A simple binary utility to vertically stack a bunch of CSV files with partially matching column headers.

Configuration

Can be configured using Config.toml to define 3 parameters:

1. csv_dir_path: the path to the directory where the csvs you want to stack are held.
2. outfile: the filename to write the stacked csv out to.
3. colnames: a list of column headers you want to select for in the stacked csv file.

Usage

I use this to aggregate individual stock trading transaction logs into a single combined csv history file.

Example

Say you have two CSV files, "foo.csv" and "bar.csv" in a relative dirctory named "csvs".

foo.csv

bar.csv

You can use the following configuration toml file to stack these csvs into "stacked.csv".

Config.toml

csv_dir_path = "csvs"
outfile = "stacked.csv"
colnames = [
"Player",
"Position",
"Number",
]

Running the binary will result in the following combined csv file "stacked.csv".

stacked.csv
