Kotools CSV

Kotools CSV is a lightweight library for managing CSV files with elegant Kotlin DSLs.

data class Person(val name: String, val age: Int, val isAdmin: Boolean = false)

suspend fun main() {
    csvWriter<Person> {
        file = "people"
        records { +Person("Nobody", 25) }
    }
    val people: List<Person> = csvReader { file = "people" }
    println(people)
}

Design goals

Lightweight

Kotools CSV just ship with what you need for manipulating CSV files, and has only 3 direct dependencies:

• doyaaaaaken/kotlin-csv for reading and writing in CSV files
• kotlin-reflect for parsing custom types to or from CSV records
• Kotlin/kotlinx.coroutines for running processes asynchronously.

Explicit error handling

Kotools CSV lets you choose explicitly how to handle errors following the design of Kotlin Standard Library: if something goes wrong, functions suffixed by OrNull will return null and other functions will throw an IllegalStateException. With this explicit design, you can orchestrate easily your application state in production.

Simply elegant

This library provides intuitive type-safe builders (also known as DSLs) for readability and maintainability purpose. So you can focus on what's important in your code, instead of trying to guess what is the good way to retrieve a file from resources or a file only present at runtime. Simplicity is key.
