    Here is the solution based on Fuzzy matching with a sensitivity of 0.5. Download example file from https://1drv.ms/x/s!Akd5y6ruJhvhuTWHGs0sOgEVhYHd?e=3nFBvL 

    let
    Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
    #"Filtered Rows" = Table.SelectRows(Source, each Text.Contains([Data], "-")),
    #"Extracted Text Before Delimiter" = Table.TransformColumns(#"Filtered Rows", {{"Data", each Text.BeforeDelimiter(_, "-"), type text}}),
    #"Removed Duplicates" = Table.Distinct(#"Extracted Text Before Delimiter"),
    #"Merged Queries" = Table.FuzzyNestedJoin(Source, {"Data"}, #"Removed Duplicates", {"Data"}, "Removed Duplicates", JoinKind.LeftOuter, [IgnoreCase=true, IgnoreSpace=true, NumberOfMatches=1, Threshold=0.5]),
    #"Expanded Removed Duplicates" = Table.ExpandTableColumn(#"Merged Queries", "Removed Duplicates", {"Data"}, {"Removed Duplicates.Data"})
in
    #"Expanded Removed Duplicates"

You can use following in a custom column and then delete the original column

try Text.Start([Project],Text.PositionOf([Project],"-")) otherwise [Project]

For column inplace replace, use following code (change Source with your last step)

Table.ReplaceValue(Source,each [Project], each try Text.Start([Project],Text.PositionOf([Project],"-")) otherwise [Project],    Replacer.ReplaceValue,{"Project"})
