Since you have this in Excel, is it possible for you to share your workbook alongwith data and query?

i am sorry working on company confidential data
i can complete this in java easy peasy but they have restricted me to query have to learn from scratch.
In second solution you removed let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t])
what does this line do?

after giving the desired output it is running endless loop
for big data take any string dump in col

take half dictonary in col 2 and try


i just copy pasted this

let
    Source = Excel.CurrentWorkbook(){[Name="Table5"]}[Content],
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}, {"Column2", type text}}),
    #"Replaced Value" = Table.ReplaceValue(#"Changed Type","",null,Replacer.ReplaceValue,{"Column2"}),
    BuffList = List.Buffer(List.RemoveNulls(#"Replaced Value"[Column2])),
    #"Added Custom1" = Table.AddColumn(#"Replaced Value", "Result", each Text.Combine(List.Intersect({BuffList,Text.Split([Column1]," ")},Comparer.OrdinalIgnoreCase)," "))
in
    #"Added Custom1"

You will need to remove complete Source line in my code and replace that with your source line. _t are generated when you use PQ's Enter Data feature to generate data rather than pulling from a source.

Use the below new code for your task

let
    Source = Excel.CurrentWorkbook(){[Name="Table5"]}[Content],
    BuffList1 = List.Buffer(Source[Column1]),
    BuffList2 = List.Buffer(List.RemoveNulls(List.ReplaceValue(Source[Column2],"",null,Replacer.ReplaceValue))),
    BuffList1Count = List.Count(BuffList1),
    GenList = List.Generate(()=>[x=Text.Combine(List.Select(BuffList2,(a)=>List.Contains(Text.Split(BuffList1{0}," "),a, Comparer.OrdinalIgnoreCase)),", "),i=0], each [i]List.Contains(Text.Split(BuffList1{i}," "),a, Comparer.OrdinalIgnoreCase)),", ")], each [x]),
    Result = Table.FromColumns(Table.ToColumns(Source)&{GenList},Table.ColumnNames(Source)&{"Result"})
in
    Result

Another issue

it is skipping words like which are enclosed with doublequotes 

example

"Demo

Insert/demo

if i try to remove all special character from the column and replace them with space

then words like can't converts into can t then t gets skip

[Syndicate_Admin]

I need to see few samples for column1 and column2 containing these kind of words...

Use this

let
    Source = Excel.CurrentWorkbook(){[Name="Table5"]}[Content],
    CharsList = {"A".."Z","a".."z"," "},
    BuffList1 = List.Buffer(Source[Column1]),
    BuffList2 = List.Buffer(List.RemoveNulls(List.ReplaceValue(Source[Column2],"",null,Replacer.ReplaceValue))),
    BuffList1Count = List.Count(BuffList1),
    GenList = List.Generate(()=>[x=Text.Combine(List.Select(BuffList2,(a)=>List.Contains(Text.Split(Text.Select(BuffList1{0},CharsList)," "),a, Comparer.OrdinalIgnoreCase)),", "),i=0], each [i]List.Contains(Text.Split(Text.Select(BuffList1{i},CharsList)," "),a, Comparer.OrdinalIgnoreCase)),", ")], each [x]),
    Result = Table.FromColumns(Table.ToColumns(Source)&{GenList},Table.ColumnNames(Source)&{"Result"})
in
    Result
