csv-to-array

csv-to-array is a Visual Studio Code extension that converts CSV files into ready-to-use C# arrays. It displays your CSV in an interactive spreadsheet-like editor, lets you modify the data, and generates valid C# code for 2D matrices or 1D vectors that you can paste directly into your project. This project has the objective to convert a csv file (automaton representation) to data type.

Features

• 📂 Open CSV in an editable grid

  • Load any .csv file into a clean interactive table inside VS Code.
  • Add or delete rows and columns.
  • Edit cell values in real-time.

• 🔢 Generate C# arrays

  • Convert your CSV into:
    • A 2D multidimensional array (T[,])
    • A 1D vector (T[])
  • Output is already formatted and ready to paste.

• 🧾 Header handling

  • Ignore first row as header (optional)
  • Ignore first column as header (optional)

• 📋 Copy to clipboard

  • One-click button to copy the generated C# code.

int[,] matrix =
{
    { 1, 2, 3 },
    { 4, 5, 6 },
    { 7, 8, 9 }
};

Generated C# 1D vector

int[] values = { 1, 2, 3, 4, 5, 6, 7, 8, 9 };
