Deedle is an easy-to-use .NET library for data frame and time series manipulation, designed for exploratory scientific programming in F# and C#. It provides advanced indexing and slicing, joining and aligning, missing value handling, grouping, aggregation, and statistics, with integrations for Excel, Parquet, Arrow, and MathNet.Numerics.
Use cases
- manipulate data frames in F# or C#
- work with time series in .NET
- load and analyze CSV data
- handle missing values in datasets
- resample and align time series data
- group and aggregate tabular data
- do exploratory data analysis in .NET
When to choose
- you're doing scientific or exploratory data programming on .NET
- you need pandas-like data frames or time series in F#/C#
- you need robust missing value handling and data alignment
When to avoid
- you need a large-scale distributed data processing engine like Spark
- you're outside the .NET ecosystem
- you need heavy machine learning pipelines rather than data manipulation
