style-xlsx-m

ℹ️ About

Style-xlsx-m is a custom XLSX (SheetJs) version library with styling from xlsx-js-style

🔌 Installation

Install npm:

npm install style-xlsx-m

Install yarn:

yarn add style-xlsx-m

Install browser:

<script src="dist/xlsx.js"></script>

🗒 Core API

• Refer to the SheetJS documentation for core API reference
• Current version of sheetjs used: 0.18.5
• Over time, will be added new and customized features.

🗒 What I added?

1. read or readFile

-- When you use read (second property put {type:'file'}) or readFile your file get cells style.

// STEP 1 
// './excample.xlsx' - is a path to your excel file.
// Second property is a option { cellStyle: true } for get cells style (but now can't get in xls format).
const workbook = XLSX.readFile('./example.xlsx',{ cellStyles: true });

// STEP 2 Create data rows worksheet 
let worksheet = [
  "!col":[ { wpx: 10 }, { wpx: 15 }, { wpx:30 } ],
  "!row":[ { hpx: 10 }, { hpx: 15 }, { hpx:30 } ],
  { v: "line\nbreak", t: "s" },
  { v: "Courier: 24", t: "s" },
  { v: 45, t: "n" },
  { v: 2023, t: "n" },
];

// STEP 3 Get workbook data with style and set workbook.Sheets.sheetname to worksheet
XLSX.utils.book_append_sheet(workbook, worksheet, false, false, sheetname);

// STEP 4 Save your file with style
XLSX.writeFile(wb, "style-xlsx-m-example.xlsm");

This example shows how you can change the contents of a file without removing its old style. (But you can't get style in xls format becouse this format don't use xml)

2. PageSetup

 const worksheet = [...]
 
 // default null
 worksheet['!pageSetup'] = { 
   paperSize: "9", // "9" for format A4
   scale: "91", // 1 - 100%
   fitToWidth: "0", // "0" || "1"
   orientation: "landscape" // "landscape" || "portrait"
 }

it can be used to print in desired format

🗒 Style API

-- Method to export file in excel with style get from xlsx-js-style (only function writeFile)

Cell Style JSON structure

• Cell styles are specified by a style object that roughly parallels the OpenXML structure.
• Style properties currently supported are: alignment, border, fill, font.

 const A1 = { v: "line\nbreak", t: "s", s:{} } // key s is a style key for your cell

 const BORDER_STYLE = 'think'

 const COLOR_STYLE = {
    rgb: 'FF0000'
 }

 // Aligment
 A1.s = {
       aligment: {
       vertical: 'bottom', // "top" or "center" or "bottom"
       horizontal : 'left', // "left" or "center" or "right"
       wrapText: false, // true or false
       textRotation: 0 // 0 to 180, or 255 // 180 is rotated down 180 degrees, 255 is special, aligned vertically
    }
 }

 const border = { 
    style: BORDER_STYLE, 
    color: COLOR_STYLE,
 }

 // Border
 A1.s = {
    border: {
        top: border, 
        bottom: border,
        left: border,
        right: border,
        diagonal: { 
            style: BORDER_STYLE, 
            color: COLOR_STYLE, 
            diagonalUp: false, // true or false
            diagonalDown: true/false // true or false
        }
    }
 }

 // Font
 A1.s = {
    font: {
        color: COLOR_STYLE,
        name: 'Calibri', // font name
        sz: '11', // font size (points)
        vertAlign: '', //  	"superscript" or "subscript"
        bold: false, // true or false
        italic: true, // true or false
        strike: false, // true or false
        underline: false, // true or false
    }
 }

 // Fill 
 A1.s = {
    fill: {
        patternType: 'none', // 'none' or 'solid'
        fgColor: COLOR_STYLE,
    }
 }

Cell Style Example

// STEP 1: Create a new workbook
const wb = XLSX.utils.book_new();

// STEP 2: Create data rows and styles
let row = [
  { v: "line\nbreak", t: "s", s: { alignment: { wrapText: true } } },
  { v: "Courier: 24", t: "s", s: { font: { name: "Courier", sz: 24 } } },
  { v: "fill: color", t: "s", s: { fill: { fgColor: { rgb: "E9E9E9" } } } },
  { v: "bold & color", t: "s", s: { font: { bold: true, color: { rgb: "FF0000" } } } },
];

// STEP 3: Create worksheet with rows; Add worksheet to workbook
const ws = XLSX.utils.aoa_to_sheet([row]);
XLSX.utils.book_append_sheet(wb, ws, "readme demo");

// STEP 4: Write Excel file to browser
XLSX.writeFile(wb, "xlsx-js-style-demo.xlsx");

COLOR_STYLE {object} Properties

Colors for border, fill, font are specified as an name/value object - use one of the following: rgb key doesn't mean it's rgb format it's a hek format.

 }
 const COLOR_STYLE = { // theme color index
    theme: 4 // (0-n) // Theme color index 4 ("Blue, Accent 1")
 }
 const COLOR_STYLE = { // tint by percent
    theme: 1, 
    tint: 0.4 // ("Blue, Accent 1, Lighter 40%")
 } 

BORDER_STYLE {string} Properties

Border style property is one of the following values:

dashDotDot, dashDot, dashed, dotted, hair, mediumDashDotDot, mediumDashDot, mediumDashed, medium, slantDashDot, thick, thin
