Hur skapar du ett nytt Excel XLSX-arkblad via Swift-biblioteket?

import XlsxReaderWriterSwift

// 1. Create a new, empty document
let document = BRAOfficeDocumentPackage()

// 2. Get the first worksheet and give it a name
guard let worksheet = document.workbook.worksheets.first as? BRAWorksheet else {
    return
}
worksheet.name = "User Data"

// 3. Write different types of data to cells
worksheet.cell(forCellReference: "A1", shouldCreate: true).stringValue = "Name"
worksheet.cell(forCellReference: "B1", shouldCreate: true).stringValue = "Score"
worksheet.cell(forCellReference: "A2", shouldCreate: true).stringValue = "Alice"
worksheet.cell(forCellReference: "B2", shouldCreate: true).integerValue = 95
worksheet.cell(forCellReference: "A3", shouldCreate: true).stringValue = "Bob"
worksheet.cell(forCellReference: "B3", shouldCreate: true).integerValue = 87

// 4. Define a file path to save the document
let documentsDirectory = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
let fileURL = documentsDirectory.appendingPathComponent("NewReport.xlsx")

// 5. Save the document to the specified path
do {
    let data = document.save()
    try data?.write(to: fileURL)
    print("Spreadsheet saved successfully at: \(fileURL.path)")
} catch {
    print("Failed to save spreadsheet: \(error)")
}

Hur tillämpar du avancerade stilar på Excel-celler med Swift-biblioteket?

// ... (after creating a worksheet and cell)

// Get or create a cell
let headerCell = worksheet.cell(forCellReference: "A1", shouldCreate: true)
headerCell.stringValue = "Sales Report"

// Access the cell's style
let style = headerCell.cellStyle()

// Configure the style
style.font.bold = true
style.font.size = 18
style.fill.foregroundColor = .blue // Background color
style.fill.patternType = .solid
style.alignment.horizontal = .center

// Apply a border to a range of cells
let borderStyle = BRABorderStyle()
borderStyle.lineStyle = .medium
borderStyle.color = .darkGray

let dataRange = worksheet.cells(inRows: 1...3, columns: 1...2)
for cell in dataRange {
    (cell as? BRACell)?.cellStyle().bottomBorder = borderStyle
}

Hur läser du data från en Excel XLSX-fil med gratis Swift API?

import XlsxReaderWriterSwift
// 1. Locate the .xlsx file in your app's bundle
guard let filePath = Bundle.main.path(forResource: "SampleData", ofType: "xlsx") else {
    print("File not found!")
    return
}

// 2. Create a BRAOfficeDocumentPackage object from the file
let document = BRAOfficeDocumentPackage.open(filePath)

// 3. Get the first worksheet
guard let worksheet = document.workbook.worksheets.first as? BRAWorksheet else {
    print("No worksheets found!")
    return
}

// 4. Read data from specific cells
if let cellA1 = worksheet.cell(forCellReference: "A1") {
    let stringValue = cellA1.stringValue() // Gets the value as a String
    print("A1: \(stringValue)")
}

if let cellB2 = worksheet.cell(forCellReference: "B2") {
    let numberValue = cellB2.floatValue() // Gets the value as a Float
    print("B2: \(numberValue)")
}

// 5. Iterate over a range of cells
for row in 1...5 {
    for column in 1...3 {
        let cellReference = "\(UnicodeScalar(64 + column)!)\(row)" // Creates refs like A1, B1, etc.
        if let cell = worksheet.cell(forCellReference: cellReference),
           let value = cell.stringValue() {
            print("\(cellReference): \(value)")
        }
    }
}
