string subFolderPath = Path.Combine(path, "Daily store sales");
string[] workbooks = Directory.GetFiles(subFolderPath, "*.xls");

DataTable dataTable = DataTableExtractor
    .Configure()
    .Workbooks(workbooks)
    .SearchLimits(searchLimitRow: 10, searchLimitColumn: 30)
    .Worksheet(worksheetIndex: 0) // Worksheet indexes in Excel are 0-based.
    .ReadOnlyTheIndicatedSheets()
    .ColumnHeader("Description")
    .ColumnHeader("Sales Value")
    .ColumnHeader("Discounts")

    .ColumnHeader("VAT")
        .ConditionToExtractRow(ConditionalsToExtractRow.HasNumericValueAboveZero)
        
    .ColumnIndex(columnIndex: 7) // Column indexes in Excel are 1-based.

    .CustomColumnHeaderMatch(cellValue => cellValue.Contains("Total"))
        .ConditionToExtractRow(cellValue => !string.IsNullOrEmpty(cellValue))
    .GetDataTable();

Documentation

This line

.SearchLimits(searchLimitRow: 10, searchLimitColumn: 30)

applies to all the worksheets to read.

To read each worksheet in each workbook, simply change this line

.ReadOnlyTheIndicatedSheets()

to this

.ReadAllWorksheets()

If after this line for example

.ColumnHeader("Description")

this other line is not specified

.ConditionToExtractRow(condition)

then the row will always be extracted (although for that all other conditions must be met).

You may want to get a collection of rows instead of a DataTable, for that, change

.GetDataTable();

with

.GetExtractedRows();

at the end.

If you need more details about the rows, for example which workbook or sheet they were extracted from, then you might want to use this line at the end.

.GetWorkbooksData();

That's all
