  • Click File > Open.
  • Click the location and folder that contains the corrupted workbook.
  • In the Open dialog box, select the corrupted workbook.
  • Click the arrow next to the Open button, and then click Open and Repair.

  • To recover as much of the workbook data as possible, pick Repair.

If Repair isn’t able to recover your data, pick Extract Data to extract values and formulas from the workbook.

If neither automatic nor manual repair works, there are some recovery methods that might help salvage your data. You can also take some preventive measures to avoid losing your work by automatically saving a backup copy of your workbook or creating a recovery file from time to time.

Set the calculation option in Excel to manual

Try changing the calculation setting from automatic to manual. Because the workbook won’t be recalculated, it may open.

  • Under New, click Blank workbook.
  • Click File > Options.
  • In the Formulas category, under Calculation options, pick Manual, and then click OK.
  • Click File > Open.
  • Locate and then double-click the corrupted workbook to open it.

Use external references to link to the corrupted workbook

To retrieve only data and not formulas or calculated values from the workbook, try using external references to link to the corrupted workbook.

  • Click File > Open.
  • Go to the folder that contains the corrupted workbook.
  • Right-click the file name of the corrupted workbook, click Copy, and then click Cancel.
  • Click File > New.
  • Under New, click Blank workbook.
  • In cell A1 of the new workbook, type =File Name!A1, where File Name is the name of the corrupted workbook that you copied in step 3, and then press Enter.
  • If the Update Values dialog box appears, select the corrupted workbook, and then click OK.
  • If the Select Sheet dialog box appears, select the appropriate sheet, and then click OK.
  • Select cell A1.
  • Click Home > Copy, or press Ctrl+C.
  • Select an area, starting in cell A1 that is approximately the same size as the range of cells that contain data in the corrupted workbook.
  • Click Home > Paste, or press Ctrl+V.
  • With the range of cells still selected, click Home > Copy again, or press Ctrl+C.
  • Click Home > the arrow below Paste, and then under Paste Values, click Values.

Pasting values removes the links to the corrupted workbook and leaves only the data.

Use a macro to extract data from a corrupted workbook

If a chart is linked to the corrupted workbook, try using a macro to extract the source data of the chart.

  • Copy the following macro code and paste it in a module sheet:

Sub GetChartValues()

Dim NumberOfRows As Integer

Dim X As Object

Counter = 2

‘ Calculate the number of rows of data.

NumberOfRows = UBound(ActiveChart.SeriesCollection(1).Values)

Worksheets(“ChartData”).Cells(1, 1) = “X Values”

‘ Write x-axis values to worksheet.

With Worksheets(“ChartData”)

.Range(.Cells(2, 1), _

.Cells(NumberOfRows + 1, 1)) = _

Application.Transpose(ActiveChart.SeriesCollection(1).XValues)

End With

‘ Loop through all series in the chart and write their values to

‘ the worksheet.

For Each X In ActiveChart.SeriesCollection

Worksheets(“ChartData”).Cells(1, Counter) = X.Name

With Worksheets(“ChartData”)

.Range(.Cells(2, Counter), _

.Cells(NumberOfRows + 1, Counter)) = _

Application.Transpose(X.Values)

End With

Counter = Counter + 1

Next

End Sub

  • Insert or delete a worksheet into your workbook right-click its sheet tab, and then rename it ChartData.
  • Select the chart from which you want to extract the underlying data values.
  • Run the GetChartValues macro.
  • The data from the chart is put on the ChartData worksheet.
