Use Sep for high-performance separated-value parsing and writing in .NET, including delimiter inference, explicit parser/writer options, and low-allocation row/column workflows.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Sep for .NET separated values

## Trigger On

- delimited data needs are performance-sensitive and allocation-aware
- project needs explicit control over separator inference, escaping, trimming, and header behavior
- reading/writing large or long-lived file pipelines in ML, ETL, or analytics workloads
- startup/perf tests require AOT/trimming-friendly CSV/TSV processing

## Install

- NuGet:
  - `dotnet add package Sep`
  - `dotnet add package Sep --version <version>`
- XML package reference:
  - `<PackageReference Include="Sep" Version="x.y.z" />`
- Verify baseline support by checking the package page:
  - [NuGet: Sep](https://www.nuget.org/packages/Sep/)
- Source:
  - [GitHub: nietras/Sep](https://github.com/nietras/Sep)

## Workflow

```mermaid
flowchart LR
  A[Input source: file/text/stream] --> B[Sep.Reader or Sep.New(...).Reader]
  B --> C[SepReaderOptions]
  C --> D[Rows -> Cols -> Span/Parse]
  D --> E[Transform and validate]
  E --> F[SepWriter via SepWriterOptions]
  F --> G[To file/text output]
```

1. Decide schema shape
   - header present or no header
   - separator known (`;`, `,`, tab, custom) or infer from first row
   - row/column quoting rules

How to install

The exact contents, by fingerprint

mdr add postpartum-genushyacinthus29/dotnet-skills/dotnet-sep@sha256:fd01d0f70d2cef8b

The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
