Try this

Answer 2

For me, the issue with "The data couldn’t be read because it isn’t in the correct format." was something to do with the specific XLSX file I was trying to use. I created a new XLSX file in Excel, and added it to my project and that worked! Then I just pasted the data I needed from the file that was giving me the error into the newly created XLSX file and it parsed!

    static func load() {
    
    guard let filePath = Bundle.main.path(forResource: "test", ofType: "xlsx", inDirectory: nil) else {
        fatalError("XLSX file not exist")
    }
    
    let file = XLSXFile(filepath: filePath)
    
    do {
                   
        let parseBooks = try? file?.parseWorkbooks()
        
        for eachBook in parseBooks! {
            
            for (name, path) in try file!.parseWorksheetPathsAndNames(workbook: eachBook) {
    
                let worksheet = try file!.parseWorksheet(at: path)
                let sharedStrings = try file!.parseSharedStrings()
                print(sharedStrings)
    
            }
        }
    } catch {
        print("Error: \(error.localizedDescription)")
    }
  }
