Serialize and deserialize ordered CSV and Fixed Length Format Files with kotlinx-serialization.

December 13, 2025 - For instance, if your data uses semicolons (;) instead of commas and encloses fields with double quotes ("), you'd typically set these options in your CSV parser. In kotlinx-serialization-csv, this is managed via CsvConfiguration:

Last line in CSV is always ignored when empty. Throws SerializationException instead of IllegalStateException in case of error.

// Complex fields can be encoded OR be split across columns. val result = csv.decodeFromString<List<Vehicle>>(""" year,make,model,trim,owner.name,owner.email,packages,packages.0,packages.1,packages.2,owner 1990,Saturn,SL2,Trim,Owner Man,ownerman@gmail.com,,A,B,C, 1991,Saturn,SL2,Unowned,,,,A,,, 1992,Saturn,SL2,null,,,,,,, 1993,Saturn,SL2,Trim,Owner Man,ownerman@gmail.com,"%[""A"",""B"",""C""]",,,, 1994,Saturn,SL2,Unowned,,,"%[""A""]",,,, 1995,Saturn,SL2,null,,,%[],,,, """.trimIndent()).also(::println) assertEquals(listOf( Vehicle(1990, "Saturn", "SL2", "Trim", OwnerInfo("Owner Man", "ownerman@

Does anyone know how to deserialize a csv containing multiarray list: Code, values 1234, [[11111, 22222], [44444, 99999]]

May 12, 2021 - It would be nice if kotlinx.serialization supported csv files/ Currently I am using jackson-dataformat-csv for this purpose: https://github.com/FasterXML/jackson-dataformat-csv

December 17, 2025 - For incoming data, Ktor's content negotiation can be set up with a custom CSV converter to deserialize incoming lists of objects directly. Conversely, when sending CSV back, you'll serialize your data and set the Content-Type to text/csv. Consider this example for handling user uploads and exports:

When your Kotlin data classes include non-primitive types or nested structures, you'll need a strategy to represent them within the flat structure of a CSV. This typically involves flattening complex fields into a single, delimited string during serialization and then parsing that string back into its original form during deserialization.

Handling CSV data in applications often involves tedious manual parsing, which is error-prone and time-consuming. This guide shows you how to efficiently serialize Kotlin data classes into CSV format and deserialize CSV strings back into Kotlin objects. You'll learn to leverage libraries like OpenCSV or Apache Commons CSV, enabling robust data handling with minimal boilerplate code.

June 16, 2026 - Kotlin serialization supports various serialization formats, such as JSON, CBOR, and Protocol buffers through different serialization format libraries. These libraries build on the core kotlinx.serialization library.
