Mastering Data Copying in .NET Interactive Notebooks

If you are working with .NET Interactive (also known as Polyglot) Notebooks, you may encounter situations where you need to export or copy data produced by your code—especially when working in languages like F-. In particular, you might want to make a list of floating-point values or tuples directly accessible for copying to the clipboard or downloading as a CSV file.

In this guide, we’ll address this common issue and offer two effective solutions: copying data to the clipboard and creating a downloadable link for your data.

Problem Overview

When executing a cell in your notebook that produces a large dataset, you might only see a limited preview of the data. For example, it may display just the first 20 values, followed by an indication that there are "more" values. This limitation can be frustrating when you want to analyze or use the full dataset outside of your notebook environment.

Proposed Solutions

Here’s how to solve the problem of exporting your data effectively:

Copying Data to Clipboard

Creating a Download Link for CSV Files

Let’s deepen our understanding of each method.

Copying Data to Clipboard

To copy the contents of a data frame (like an F- list or a DataFrame) to the clipboard, you can leverage the TextCopy package. This package allows you to directly interact with the clipboard from your notebook.

Step-by-Step Guide

Creating a Download Link for CSV Files

If you want to download your data instead of just copying it, you can generate a downloadable link directly in your notebook. This is especially useful for sharing data with others.

Step-by-Step Instructions

Prepare Your CSV Data:
Convert your CSV string into a format suitable for a download link:
