What is a CSV列の入れ替え?

このツールは、CSVデータの列の位置を入れ替えることでデータを再構成します。列を入れ替えることで、頻繁に使用するデータをまとめて配置したり、先頭に配置したりすることで、データの比較や編集が容易になり、CSVファイルの読みやすさが向上します。例えば、最初の列を最後の列と入れ替えたり、2番目の列を3番目の列と入れ替えたりすることができます。列の位置に基づいて列を入れ替えるには、

CSV列の入れ替え 例

Move the Key Column to the First Position

In this example, we use our CSV column swapping tool to bring the most important information to the first column. As we are planning to go on vacation soon, in the input of the tool, we load data about national parks that include their names and locations. To decide, which is the closest park to us, we need to see the parks location first, therefore, we swap the first and second data columns so that the "location" column is at the beginning of the CSV data.

Input
park_name,location
Yellowstone,Wyoming
Yosemite,California
Grand Canyon,Arizona
Rocky Mountain,Colorado
Zion Park,Utah
Output
location,park_name
Wyoming,Yellowstone
California,Yosemite
Arizona,Grand Canyon
Colorado,Rocky Mountain

Reorganize Columns in Vitamins CSV

In this example, a lab intern made a mistake and created a corrupted CSV file with mixed-up columns and missing data. To fix the file, we swap the columns based on the headers "Vitamin" and "Function" so that the "Vitamin" column becomes the first in the output data. We also fill the incomplete CSV data by adding a custom asterisk "*" symbol in place of missing values.

Input
Function,Fat-Soluble,Vitamin,Sources
Supports vision,Fat-Soluble,A,Carrots
Immune function,Water-Soluble,C,Citrus fruits
Bone health,Fat-Soluble,D,Fatty fish
Antioxidant,Fat-Soluble,E,Nuts

Place Columns Side by Side for Analysis

In this example, we change the order of columns in a CSV dataset to have the columns essential for analysis adjacent to each other. We match the "ScreenSize" column by its name and place it in the second-to-last position "-2". This groups the "ScreenSize" and "Price" columns together, allowing us to easily compare and choose the phone we want to buy. We also remove empty lines and specify that lines starting with the "#" symbol are comments and should be left as is.

Input
Brand,Model,ScreenSize,OS,Price

Apple,iPhone 15 Pro Max,6.7″,iOS,$1299
Samsung,Galaxy S23 Ultra,6.8″,Android,$1199
Google,Pixel 7 Pro,6.4″,Android,$899
