VBA macro for removing unwanted paragraph break

[fngb3]

I am in Word and have a lot of text pulled from a PDF that has inserted breaks in to lines. For example it may go

"The quick brown fox jumps
over the lazy dog."

...and what I'd want, obviously, is that sentence all on one line

e.g. "The quick brown fox jumps over the lazy dog."

Essentially, every time there is a paragraph break (I believe they are Char(10) or vbLf) followed by a lowercase letter, I want to change that paragraph character to a simple space.

I am completely new to visual basic. I have some Frankenstein-monster-esque chunks of code that I've pulled from various places on the internet, but I'm afraid that sharing it would probably limit people's recommendations on how to do what at least appears to be a fairly simple thing by making them try to use or fix the structure of what I've got, when I'm not the least bit attached to it anyway.

Can someone please point me in the right direction here?
Much obliged

Go ahead and share the code you've currently got and you'll get more help instead of us working in the dark. :)

Sub ChangeCase1()
Dim vFindLineBreak As Variant
Dim vReplace As Variant
Dim orng As Range

'This is what I found that seems to detect a lowercase character from a to z.
Function FirstLower(strI n As String) As String
Dim objRegex As Object
Dim objRegM As Object
Set objRegex = CreateObject("v bscript.regexp" )
With objRegex
.Pattern = "[a-z]"
.ignorecase = False
If .test(strIn) Then
Set objRegM = .Execute(strIn) (0)
FirstLower = objRegM.firstin dex + 1
Else
FirstLower = "no match"
End If
End With
End Function

'I want this to find instances where a line break is followed by a lowercase character, and replace those two things with a space.
vFindText = vbLf + FirstLower

vReplaceText = " "

Next
End Sub

Or, and this seems more promising.

Sub findlower()

Selection.Find. ClearFormatting
Selection.Find. Replacement.Cle arFormatting
With Selection.Find
.Text = "^13 + ([a-z])"
.Replacement.Te xt = " \1"
.Forward = True
.Wrap = wdFindContinue
.Format = False
.MatchCase = False
.MatchWholeWord = False
.MatchWildcards = False
.MatchSoundsLik e = False
.MatchAllWordFo rms = False
End With
Selection.Find. Execute
With Selection
If .Find.Forward = True Then
.Collapse Direction:=wdCo llapseStart
Else
.Collapse Direction:=wdCo llapseEnd
End If
.Find.Execute Replace:=wdRepl aceOne
If .Find.Forward = True Then
.Collapse Direction:=wdCo llapseEnd
Else
.Collapse Direction:=wdCo llapseStart
End If
.Find.Execute
End With
End Sub

I think you can accomplish what you're after by changing this line:

Pattern = "[a-z]"

to this:

Pattern = "[a-z][\r\n]"

In case you're wondering how I tested this, I used the following code in Visual Studio using VB.NET, but the regex should still be the same.

'Create a test string with a line feed (vbLf) in the middle
Dim testString As String = "The quick brown fox jumps" & vbLf & " over the lazy dog."

'Display test string in a window
MsgBox(testString)

'Using regular expressions, replace the line feed if it follows lowercase letter
testString = System.Text.RegularExpressions.Regex.Replace(testString, "[a-z][\r\n]", "")

'Display new test string format in a window
MsgBox(testString)
