How to Unhide All Rows in Excel

How Do I Use the Ribbon Button to Hide Rows?

You can also hide rows in Excel using the Ribbon button located at the top of the Excel sheet. This method is particularly useful when you're already working with other formatting options or when teaching new users who prefer visual interfaces.

Step 1: Click the Format button in the Cells group under the Home tab.

Step 2: Choose Hide Rows from the Hide & Unhide menu under Visibility.

Excel Hide & Unhide

As another option, you can select Home > Format > Row Height and enter 0 in the field for Row Height. In either case, the selected rows will immediately be hidden from view. This approach mirrors how developers might programmatically set cell properties when working with Excel automation.

What's the Fastest Way Using Right-Click?

If you don't want to search for the Hide command on the ribbon, you can access it from the context menu by right-clicking on the column or row header and choosing the Hide option. This method is particularly efficient when you're working with specific rows and want quick access to row-specific operations.

Hide in the context menu

This context menu approach is similar to how developers might interact with Excel ranges programmatically, providing direct access to the elements you want to manipulate.

Which Keyboard Shortcut Hides Rows Quickly?

You can also hide rows in an Excel document using a keyboard shortcut by pressing Ctrl + 9 to hide all selected rows. This shortcut is especially valuable for power users and developers who prefer keyboard-driven workflows. When you're creating Excel files programmatically, understanding these shortcuts helps you design better user interfaces that mirror familiar Excel behaviors.

Where's the Unhide Option in the Ribbon?

You can unhide rows using the Ribbon button available at the top of the Excel sheet. This method provides a consistent interface across different Excel versions and is particularly helpful when dealing with complex Excel workbooks.

Step 1: Click the Format button in the Cells group under the Home tab.

Step 2: Choose Unhide Rows from the Hide & Unhide menu under Visibility.

Can I Unhide Rows Using Right-Click?

You can unhide rows using an option from the context menu by right-clicking the chosen rows and choosing "Unhide". When selecting rows around hidden ones, make sure to include the row numbers before and after the hidden rows. This technique is particularly useful when working with specific ranges in your Excel documents.

What's the Keyboard Shortcut to Unhide All Rows?

You can also unhide all hidden rows in an Excel document using keyboard shortcuts by pressing Ctrl + Shift + 9, which helps make hidden rows visible again in the spreadsheet. This shortcut complements the hide shortcut (Ctrl + 9) and provides a quick way to toggle visibility when analyzing Excel data.

How Do I Hide Rows Programmatically with IronXL?

IronXL lets you hide row numbers in Excel with just a few lines of code. This approach is particularly useful when building applications that need to automate Excel operations or when processing multiple files. The code below shows an example of hiding a row in Excel.

using IronXL;

// Load an existing Excel workbook
// This creates a WorkBook object that represents the entire Excel file
WorkBook wb = WorkBook.LoadExcel("sample1.xlsx");

// Select the worksheet by name
// You can also use GetWorkSheet by index: wb.GetWorkSheet(0)
WorkSheet ws = wb.GetWorkSheet("Sheet1");

// Hide the second row (index 1, as it's zero-based)
// The Hidden property controls the visibility of the row
ws.GetRow(1).Hidden = true;

// You can also hide multiple rows in a loop
for (int i = 5; i <= 10; i++)
{
    ws.GetRow(i).Hidden = true;  // Hides rows 6-11
}

// Save changes to the Excel file
// This overwrites the original file
wb.SaveAs("sample1.xlsx");

// Alternatively, save with a different name
// wb.SaveAs("sample1_with_hidden_rows.xlsx");

using IronXL;

// Load an existing Excel workbook
// This creates a WorkBook object that represents the entire Excel file
WorkBook wb = WorkBook.LoadExcel("sample1.xlsx");

// Select the worksheet by name
// You can also use GetWorkSheet by index: wb.GetWorkSheet(0)
WorkSheet ws = wb.GetWorkSheet("Sheet1");

// Hide the second row (index 1, as it's zero-based)
// The Hidden property controls the visibility of the row
ws.GetRow(1).Hidden = true;

// You can also hide multiple rows in a loop
for (int i = 5; i <= 10; i++)
{
    ws.GetRow(i).Hidden = true;  // Hides rows 6-11
}

// Save changes to the Excel file
// This overwrites the original file
wb.SaveAs("sample1.xlsx");

// Alternatively, save with a different name
// wb.SaveAs("sample1_with_hidden_rows.xlsx");

The example above loads an existing Excel document using the WorkBook.LoadExcel method by providing the path and file name. Once the Excel document loads in the WorkBook object, you can specify a particular Excel worksheet using the WorkBook method GetWorkSheet and pass the sheet name as a parameter. This creates a WorkSheet object, which provides functionality for the entire worksheet.

After getting the WorkSheet object, you can select a row using the method GetRow by passing the row index as a parameter. This allows you to use the boolean value from the Hidden property and set it to true, which can hide and unhide rows in an Excel document. The code above demonstrates hiding the second row of the Excel document.

How Do I Unhide Multiple Rows Using IronXL?

The following code can unhide multiple rows in Excel, which is particularly useful when you need to reveal all data for data analysis or reporting purposes:

using IronXL;

// Load an existing Excel workbook
WorkBook wb = WorkBook.LoadExcel("sample1.xlsx");

// Select the worksheet
WorkSheet ws = wb.GetWorkSheet("Sheet1");

// Unhide the second row
ws.GetRow(1).Hidden = false;

// Unhide all rows in the worksheet
// This is useful when you want to ensure all data is visible
int maxRows = ws.RowCount;
for (int i = 0; i < maxRows; i++)
{
    var row = ws.GetRow(i);
    if (row != null)
    {
        row.Hidden = false;
    }
}

// Alternative: Unhide a specific range of rows
for (int i = 0; i <= 20; i++)
{
    ws.GetRow(i).Hidden = false;  // Unhides first 21 rows
}

// Save changes to the Excel file
wb.SaveAs("sample1.xlsx");

// You can also export the unhidden data to other formats
// wb.SaveAsCsv("unhidden_data.csv");
// wb.SaveAsJson("unhidden_data.json");

using IronXL;

// Load an existing Excel workbook
WorkBook wb = WorkBook.LoadExcel("sample1.xlsx");

// Select the worksheet
WorkSheet ws = wb.GetWorkSheet("Sheet1");

// Unhide the second row
ws.GetRow(1).Hidden = false;

// Unhide all rows in the worksheet
// This is useful when you want to ensure all data is visible
int maxRows = ws.RowCount;
for (int i = 0; i < maxRows; i++)
{
    var row = ws.GetRow(i);
    if (row != null)
    {
        row.Hidden = false;
    }
}

// Alternative: Unhide a specific range of rows
for (int i = 0; i <= 20; i++)
{
    ws.GetRow(i).Hidden = false;  // Unhides first 21 rows
}

// Save changes to the Excel file
wb.SaveAs("sample1.xlsx");

// You can also export the unhidden data to other formats
// wb.SaveAsCsv("unhidden_data.csv");
// wb.SaveAsJson("unhidden_data.json");

To unhide specific rows, follow the steps mentioned above and modify the instructions by selecting the row through the method GetRow, either by passing the row index as a parameter or by specifying the row. Then set the boolean value of Hidden to false. This functionality is particularly useful when working with imported data where some rows might be hidden by default.
