hello good afternoon
I would like some help with this code, if possible, it enters the site and extracts data from just one table, how can I copy all the tables on the site?

I'm using the code below

I tried to use the code in the attached image ("/html/body/div[1]") to select them all, but I got an error

Sub ExtractTabs()
Set driver = New ChromeDriver
Dim dest As range
Set dest = range("A1")

driver.Get "https://www2.bmf.com.br/pages/portal/bmfbovespa/lumis/lum-tipo-de-participante-ptBR.asp"

Dim tabel As WebElement

Set tabel = driver.FindElementByXPath("/html/body/div[1]/div[2]/div/table[1]")

If tabel Is Nothing Then
MsgBox "element not found"
Else
tabel.AsTable.ToExcel dest
End If

driver.Quit
End Sub

Does the VLOOKUP table have to be sorted?
No! when you are using an exact match, the VLOOKUP table can be in any order. Best-selling items at the top is actually the best.
Load the following Code into an empty standard module of your vba:
VBA Code:
Dim WPage As Object

Sub ExtractTabs()
'
Set WPage = CreateObject("Selenium.WebDriver")
WPage.Start "Chrome"

myUrl = "https://www2.bmf.com.br/pages/portal/bmfbovespa/lumis/lum-tipo-de-participante-ptBR.asp"
Call GetAllTablesArr(myUrl, 1, 1)       'Url, Row, Column

WPage.Quit
Set WPage = Nothing
End Sub




Sub GetAllTablesArr(ByVal myUrl As String, Optional rNum0 As Long = 1, Optional cNum0 As Long = 1)
Dim TBColl As Object
Dim I As Long, j As Long, myTim As Single
Dim RNum As Long, CNum As Long
    
Dim TArr

WPage.Get myUrl
'
myTim = Timer
'
Set TBColl = WPage.FindElementsByTag("table")
RNum = rNum0: CNum = cNum0
'
For I = 1 To TBColl.Count               'Scan delle Tabelle presenti
    TArr = TBColl(I).AsTable.Data
    RNum = RNum + 1
    Cells(RNum, CNum).Value = "## Table " & I
    If (UBound(TArr) * UBound(TArr, 2)) > 0 Then
        Cells(RNum + 1, CNum).Resize(UBound(TArr), UBound(TArr, 2)).Value = TArr
    End If
    RNum = RNum + UBound(TArr) + 1
    DoEvents
Next I
Debug.Print "FINE", RNum, Format(Timer - myTim, "0.00"), myUrl
End Sub
Then start Sub ExtractTabs

The output will be written starting from Row2 /Column2 of the active sheet

It worked great!
Let me ask you a question:
Would it be possible to make 2 adjustments,

first: is it possible to keep the main name of each table instead of "## Table 1, ## Table 2 " etc?

I'll attach an image as an example.

Second :
Would it be possible to keep the same formatting of numbers in the standard of my country?

I will attach an image as an example.

Lets modify the code for the Sub GetAllTablesArr as follows:
VBA Code:
Sub GetAllTablesArr(ByVal myUrl As String, Optional rNum0 As Long = 1, Optional cNum0 As Long = 1)
Dim TBColl As Object, TBCap As Object
Dim I As Long, j As Long, myTim As Single
Dim RNum As Long, CNum As Long
Dim TArr
'
WPage.Get myUrl
'
myTim = Timer
'
Set TBColl = WPage.FindElementsByTag("table")
RNum = rNum0: CNum = cNum0
'
For I = 1 To TBColl.Count               'Scan delle Tabelle presenti
    TArr = TBColl(I).AsTable.Data
    RNum = RNum + 2
    Set TBCap = TBColl(I).FindElementsByTag("Caption")
    If TBCap.Count > 0 Then
        Cells(RNum, CNum).Value = "##" & I & " " & TBCap(1).Text    'Caption, if any
    Else
        Cells(RNum, CNum).Value = "## Table " & I                   'Standard heads
    End If
    If (UBound(TArr) * UBound(TArr, 2)) > 0 Then
        Cells(RNum + 1, CNum).Resize(UBound(TArr) + 5, UBound(TArr, 2) + 1).ClearContents
        Cells(RNum + 1, CNum).Resize(UBound(TArr), UBound(TArr, 2)).NumberFormat = "@"
        Cells(RNum + 1, CNum).Resize(UBound(TArr), UBound(TArr, 2)).Value = TArr
    End If
    RNum = RNum + UBound(TArr) + 1
    DoEvents
Next I
Debug.Print "FINE", RNum, Format(Timer - myTim, "0.00"), myUrl
End Sub
This will use the table "Caption", if available, or will use the default ##Table x; also the data are copied as text, that is how they looks on the web.

The aim of that code is importing the tables, not "presenting them"; so alignment, data conversion, formatting is job for you :biggrin:
