should help you out I import my data from multiple Excel files into R, and my data looks like this in R (there could be 100+ files each day): , This should do the trick:
code :

df_list %>% 
  map_dfr(filter, Code == 7229) %>% 
  write_csv(path = "/INSERT/PATH/HERE/text.csv")
df_1 <- tribble(
  ~ST,  ~Code, ~Emp, ~Employee, ~Pay.Code,               ~Hours, ~Gross,

How can I extract data from multiple files in a folder of excel

How can I extract data from multiple files in a folder of excel

it fixes the issue You can use the FileSystemObject to get all the name of the files you need. and then do want you want in a loop
code :
Dim fso As Object
Dim folder As Object
Dim file As Object
Dim xlWb As Workbook

Set fso = CreateObject("Scripting.FileSystemObject")
Set folder = fso.GetFolder("your\folder")

for each file in folder.files
  Set xlWb = Workbooks.Open(file.Path & "\" & file.Name)
  'your code here

I think the issue was by ths following , First of all - your Test.xlsx should be a xlsm if your code is in there. All the other files (just with data) - if they have no code - should be xlsx instead.
Now - try this code with the above changes in a module in Test.xlsm:
code :
Sub openFilesExtractData()

    Dim folderPath As String, path As String, yourText As String
    Dim currWbSh As Worksheet
    Dim i As Long, j As Long, k As Long

    folderPath = ThisWorkbook.path

    path = folderPath & "\*.xlsx"

    Filename = Dir(path)

    j = ThisWorkbook.Worksheets(1).UsedRange.Rows.count + 1
    k = 1

    Do While Filename <> ""

        If Filename <> ThisWorkbook.Name And Filename <> "" Then

            Workbooks.Open folderPath & "\" & Filename

            Set currWbSh = Workbooks(Filename).Worksheets(1)

            yourText = InputBox("What are you searching for?")

            For i = 1 To currWbSh.UsedRange.Rows.count

                Select Case yourText

                    Case currWbSh.Cells(i, 5):

                        ThisWorkbook.Worksheets(1).Cells(j, k) = yourText
                        k = k + 1

                    Case currWbSh.Cells(i, 6):

                        ThisWorkbook.Worksheets(1).Cells(j, k) = yourText
                        k = k + 1

                End Select

                If i = currWbSh.UsedRange.Rows.count And k <> 1 Then

                    ThisWorkbook.Worksheets(1).Cells(j, k) = Filename
                    j = j + 1

                End If

            Next i

            Workbooks(Filename).Close False

        End If

        Filename = Dir()
        k = 1
        j = ThisWorkbook.Worksheets(1).UsedRange.Rows.count + 1

help you fix your problem If you're not opposed to having the outputted excel file as a .xlsx rather than .xls, I'd recommend making use of some of the features of Pandas. In particular pandas.read_csv() and DataFrame.to_excel()
I've provided a fully reproducible example of how you might go about doing this. Please note that I create 2 .txt files in the first 3 lines for the test.
code :
import pandas as pd
import numpy as np
import glob

# Creating a dataframe and saving as test_1.txt/test_2.txt in current directory
# feel free to remove the next 3 lines if yo want to test in your directory
df = pd.DataFrame(np.random.randn(10, 3), columns=list('ABC'))
df.to_csv('test_1.txt', index=False)
df.to_csv('test_2.txt', index=False)

txt_list = [] # empty list
sheet_list = [] # empty list

# a for loop through filenames matching a specified pattern (.txt) in the current directory
for infile in glob.glob("*.txt"): 
    outfile = infile.replace('.txt', '') #removing '.txt' for excel sheet names
    sheet_list.append(outfile) #appending for excel sheet name to sheet_list
    txt_list.append(infile) #appending for '...txt' to txtt_list

writer = pd.ExcelWriter('summary.xlsx', engine='xlsxwriter')

# a for loop through all elements in txt_list
for i in range(0, len(txt_list)):
    df = pd.read_csv('%s' % (txt_list[i])) #reading element from txt_list at index = i 
    df.to_excel(writer, sheet_name='%s' % (sheet_list[i]), index=False) #reading element from sheet_list at index = i

I wish this help you As per PEH's and my comments earlier, here is an approach
Copy the below UDF in a module:
code :
Sub LookForWordDocs()
    Dim sFoldPath As String: sFoldPath = "c:\temp\"     ' Change the path. Ensure that your have "\" at the end of your path
    Dim oFSO As New FileSystemObject                    ' Requires "Microsoft Scripting Runtime" reference
    Dim oFile As file

    ' Loop to go through all files in specified folder
    For Each oFile In oFSO.GetFolder(sFoldPath).Files

        ' Check if file is a word document. (Also added a check to ensure that we don't pick up a temp Word file)
        If (InStr(1, LCase(oFSO.GetExtensionName(oFile.Path)), "doc", vbTextCompare) > 0) And _
                (InStr(1, oFile.Name, "~$") = 0) Then

            ' Call the UDF to copy from word document
            CopyTableFromWordDoc oFile

        End If


End Sub
Sub CopyTableFromWordDoc(ByVal oFile As file)
    Dim oWdApp As New Word.Application                      ' Requires "Microsoft Word .. Object Library" reference
    Dim oWdDoc As Word.Document
    Dim oWdTable As Word.Table
    Dim oWS As Worksheet
    Dim lLastRow$, lLastColumn$

    ' Code to copy table from word document to this workbook in a new worksheet
    With ThisWorkbook

        ' Add the worksheet and change the name to what file name is
        Set oWS = .Worksheets.Add
        oWS.Name = oFile.Name

        ' Open Word document
        Set oWdDoc = oWdApp.Documents.Open(oFile.Path)

        ' Set table to table 3 in the document
        Set oWdTable = oWdDoc.Tables(1)

        ' Copy the table to new worksheet
        oWS.Range("A1").PasteSpecial xlPasteValues, xlPasteSpecialOperationNone

        ' Close the Word document
        oWdDoc.Close False

        ' Close word app

    End With

it should still fix some issue I am not using read_excel and you did not provide a MRE so I could not test it, but you could try this.
code :
df.list <- lapply(file.list, read_excel, sheet=1, range="E6:E7", col_names=FALSE, col_types = NULL))
