FileHelpers is a free, MIT-licensed .NET library for reading and writing strongly typed records from fixed-length or delimited flat files, strings, and streams. Records are mapped via annotated C# classes, with support for converters, error handling, events, sorting of large files, and master-detail processing.
Use cases
- parse csv files into strongly typed c# objects
- read fixed length flat files like cobol output
- write delimited or fixed-width text files from .NET objects
- convert between file formats such as fixed length to csv
- import flat file data into a data warehouse or etl pipeline
- parse log files with a defined record layout
- sort large flat files in .NET
When to choose
- you are on .NET/.NET Standard and need typed, attribute-based mapping of flat file records
- you need both delimited and fixed-length record support with converters and error handling
- you want a mature, free library for flat file import/export without heavy dependencies
When to avoid
- you need Excel/Access/SqlServer storage on .NET Core - those features are not ported to .NET Standard
- you need dynamic runtime class building (ClassBuilder, SmartFormatDetector) on .NET Core
- you need a general-purpose CSV library with non-.NET platforms
