MiniExcel is a lightweight .NET library (with a Rust variant) for reading and writing Excel XLSX and CSV files using row-by-row streaming to minimize memory usage. It avoids loading entire workbooks into memory, preventing out-of-memory issues on large spreadsheets.
Use cases
- export large datasets to excel without running out of memory
- read xlsx files row by row in .net
- generate excel reports from c#
- import csv and xlsx data into dotnet applications
- process huge spreadsheets with low memory footprint
- convert ienumerable to excel file
When to choose
- you need to read or write large Excel/CSV files in .NET with minimal memory usage
- you want a simple, fast API without the overhead of full Excel object models
- you need cross-platform spreadsheet processing without Excel installation
When to avoid
- you need advanced Excel features like charts, pivot tables, or cell formatting manipulation
- you need to modify existing complex workbooks in place
- you are not working in .NET or Rust
