the 'find & Replace" function doesn't work in ACCESS 2019 Pro

Where are you trying to perform a find & replace? (Form, Table, Query, VBA/VBE, ... ???)

Did it work previously? If so, what has changed?

Can you provided detailed reproduction steps for us to try and replicate the issue. Perhaps a screen recording showing the issue.

Have you tried updating/rolling back your build?

Have you tried performing an Office/Access repair?

You might find the following function useful:

Public Function MultiReplace(varInput, ParamArray varReplacements())

    ' call like this:

' MultiReplace("The cat sat on the mat","cat", "mouse", "mat", "house")

' to return this:

' The mouse sat on the house

    Const MESSAGETEXT = "Uneven number of replacements parameters."

    Dim n As Integer

    Dim varOutput As Variant

    Dim intParamsCount As Integer

    If Not IsNull(varInput) Then

        intParamsCount = UBound(varReplacements) + 1

        If intParamsCount Mod 2 = 0 Then

            varOutput = varInput

            For n = 0 To UBound(varReplacements) Step 2

                varOutput = Replace(varOutput, varReplacements(n), varReplacements(n + 1))

            Next n

        Else

            MsgBox MESSAGETEXT, vbExclamation, "Invalid Operation"

        End If

    End If

    MultiReplace = varOutput

End Function

You'd call it in an UPDATE query to make multiple replacements in each row simultaneously.

Massive thanks, I’ll try it 🙏
