Cómo convertir una tabla en un rango en Excel

How to Create a Table?

There are many ways to create or convert a range to a table range in Excel. To insert a table in Excel, click any single cell within your data set, and do any of the following:

1. On the Insert menu tab, in the Tables section group, click the Table option. A default style table will be inserted.

   Insert a New Table in Excel with Default Styles

2. On the Home menu tab, in the Styles section group, click Format as Table, and select one of the predefined table styles. You can choose any banded rows style.

   Apply a predefined format to an existing Excel spreadsheet table

3. Another option and the fastest way to create an Excel table is by pressing the keyboard shortcut: Ctrl + T.

Whichever method you choose, the Create Table dialog box appears. Excel automatically selects the data range. Verify the selected range, then check/uncheck the "My table has headers" option, and click OK.

Format the Table with Excel preselected style

As a result, a nicely formatted table is created in the worksheet.

The filter arrows allow us to filter and sort the data in the table based on your criteria. While scrolling, the column headers box is visible. New data can be included using automatic table expansion, Quick totals, Calculating table data with ease are some prominent table features.

Now we know how to convert a regular range of cells to a table style. At some point, we might need to remove table formatting and convert the table to a normal range without losing any data and formulas. So let's have a look at how to convert an Excel table to a range.

How to Convert Table Style to a Normal Range?

There are two ways to convert a table to a cell range in Excel.

If you want to remove a table without losing the table data, table formatting, or structured references, you can follow the below steps:

1. Go to the Table Design tab under Table Tools > Tools group, and click Convert to Range.

   Converting a Styled Table into a Normal Range using the Menu Bar options

2. Alternatively, right-click anywhere within the table, and click Table > Convert to Range.

   Converting a Styled Table into a Normal Range using the Context Menu

This is how you can convert the data of a table to a range. Notice that the arrows are removed from the range but the data and formatting are preserved.

The IronXL C# Library

IronXL is a .NET library that facilitates reading and editing Microsoft Excel documents with C# without Microsoft Excel or Interop. IronXL can read and manipulate Excel files with accuracy and fast performance. It supports all .NET components, along with platforms such as Android, Xamarin, Linux, Azure, AWS, macOS, Docker, and MAUI.

With a few lines of code, developers can perform all Excel-related tasks without any complication. These tasks include adding two cells, adding rows and columns of data to Excel tables, and applying functions across rows and columns, among others.

IronXL Feature Set

• Load, read, and edit data — from XLS/XLSX/CSV/TSV
• Saving and exporting — to XLS/XLSX/CSV/TSV/JSON
• System.Data Objects — work with Excel Spreadsheets as System.Data.DataSet and System.Data.DataTable objects.
• Formulas — works with Excel formulas. Formulas get recalculated whenever the sheet is edited.
• Ranges — easy to use ["A1:B10"] syntax.
• Sorting — it can sort rows, columns, and ranges within a table or normal range.
• Styling — font, font size, cell style, alignments, background color, and many more styling options are available.

Below are some code examples of C# code to manipulate Excel files:

using IronXL;

public class ExcelExample
{
    public static void Main()
    {
        // Load an existing Excel workbook
        WorkBook workbook = WorkBook.Load("test.xlsx");

        // Choose the default worksheet in the workbook
        WorkSheet worksheet = workbook.DefaultWorkSheet;

        // Set formulas for various cells
        worksheet["A1"].Formula = "SUM(B8:C12)"; // Sum cells B8 to C12
        worksheet["B8"].Formula = "=C9/C11"; // Divide value in C9 by value in C11
        worksheet["G30"].Formula = "MAX(C3:C7)"; // Find the maximum value from cells C3 to C7

        // Force recalculating all formulas in all sheets
        workbook.EvaluateAll();

        // Retrieve calculated value from a cell
        string formulaValue = worksheet["G30"].Value.ToString(); // e.g., 52

        // Retrieve the formula as a string from a cell
        string formulaString = worksheet["G30"].Formula; // e.g., "MAX(C3:C7)"

        // Save changes with updated formulas and calculated values
        workbook.Save();
    }
}

using IronXL;

public class ExcelExample
{
    public static void Main()
    {
        // Load an existing Excel workbook
        WorkBook workbook = WorkBook.Load("test.xlsx");

        // Choose the default worksheet in the workbook
        WorkSheet worksheet = workbook.DefaultWorkSheet;

        // Set formulas for various cells
        worksheet["A1"].Formula = "SUM(B8:C12)"; // Sum cells B8 to C12
        worksheet["B8"].Formula = "=C9/C11"; // Divide value in C9 by value in C11
        worksheet["G30"].Formula = "MAX(C3:C7)"; // Find the maximum value from cells C3 to C7

        // Force recalculating all formulas in all sheets
        workbook.EvaluateAll();

        // Retrieve calculated value from a cell
        string formulaValue = worksheet["G30"].Value.ToString(); // e.g., 52

        // Retrieve the formula as a string from a cell
        string formulaString = worksheet["G30"].Formula; // e.g., "MAX(C3:C7)"

        // Save changes with updated formulas and calculated values
        workbook.Save();
    }
}
