Column widths are Otherwise, GC will collect/dispose XpsDocument and DocumentViewer will no longer work. strings found in the code (Hex, Base64, Dridex) with their decoded value. However, for some formats such as PowerPoint 97-2003, this method will try to cycle specified values to the desired type. Excel into thinking that the file is potentially a CSV or TSV file, even if it (MS Office 2007+), MHTML or Word 2003 XML. script tags should be used to include the axios and xlsx standalone builds: The parser covers a wide gamut of common spreadsheet file formats to ensure that parsed, the column objects store the pixel width in the wpx field, character Standard rules apply **, Comment (only applicable for XLS/XLSX/XLSB), epoch: 0/false for 1900 system, 1/true for 1904, Warn or strip personally identifying info on save, Input data encoding (see Input Type below), If true, plain text parsing will not parse values **, If specified, use code page when appropriate **, If specified, use the string for date code 14 **, If true, only parse enough to get book metadata **, If true, only parse enough to get the sheet names, If defined and file is encrypted, use password **, If true, throw errors on unexpected file features **, If specified, only parse specified sheets **, string: JS string (characters interpreted as UTF8), string: path of file that will be read (nodejs only), BIFF 5/8 or protected XLSX/XLSB or WQ3/QPW or XLR, SpreadsheetML / Flat ODS / UOS1 / HTML / plain text, XLSB or XLSX/M or ODS or UOS2 or NUMBERS or text, one of the first 1024 characters is a comma, Output data encoding (see Output Type below), Type of Workbook (see below for supported formats), Name of Worksheet for single-sheet formats **, Use ZIP compression for ZIP-based formats **, Override workbook properties when writing **, Override theme XML when writing XLSX/XLSB/XLSM **, ArrayBuffer, fallback array of 8-bit unsigned int, string: path of file that will be created (nodejs only), Use specified date format in string output, Use specified cell as starting point (see below), Start from the first column at specified row (0-indexed), Append to bottom of worksheet starting on first column, If true, do not include header row in output, If true, every cell will hold raw strings, If true, hidden rows and cells will not be parsed, "Field Separator" delimiter between fields, "Record Separator" delimiter between rows, Remove trailing field separators in each record **, Skips hidden rows/columns in the CSV output, Use raw values (true) or formatted strings (false), Use specified value in place of null or undefined, Use worksheet range but set starting row to the value, Use specified range (A1-style bounded range string), Row object keys are literal column labels, Use specified strings as keys in row objects, Excel 2003-2004 XML Format (XML "SpreadsheetML"), Numbers 3.0+ / iWork 2013+ Spreadsheet (NUMBERS), Uniform Office Format Spreadsheet ( UOS1/UOS2), Quattro Pro Spreadsheet (WQ1/WQ2/WB1/WB2/WB3/QPW), Works 1.x-3.x DOS / 2.x-5.x Windows Spreadsheet (WKS), raw source files that make up the final script, dist files for web browsers and nonstandard JS environments, demo projects for platforms like ExtendScript and Webpack, test files (pulled from the test files repository), codepage library skipped (no support for XLS encodings), no support for XLSB / XLS / Lotus 1-2-3 / SpreadsheetML 2003 / Numbers, In some cases, sheets may be parsed even if, Excel aggressively tries to interpret values from CSV and other plain text. should be used to write the file data to a Buffer for use with XLSX.write: writeFile uses Deno.writeFileSync under the hood: Applications writing files must be invoked with the --allow-write flag. representation of the core concepts of a workbook.
