lynMarkdigRenderTest12 1.0.0

Simplexcel

This is a simple .xlsx generator library for .net 4.5, .NET Standard 1.3 (or higher), and .NET Standard 2.0.

It does not aim to implement the entirety of the Office Open XML Workbook format and all the small and big features Excel offers.
Instead, it is meant as a way to handle common tasks that can't be handled by other workarounds (e.g., CSV Files or HTML Tables) and is fully supported under ASP.net (unlike, say, COM Interop which Microsoft explicitly doesn't support on a server).

Features

• You can store numbers as numbers, so no more unwanted conversion to scientific notation on large numbers!
• You can store text that looks like a number as text, so no more truncation of leading zeroes because Excel thinks it's a number
• You can have multiple Worksheets
• You have basic formatting: Font Name/Size, Bold/Underline/Italic, Color, Border around a cell
• You can specify the size of cells
• Workbooks can be saved compressed or uncompressed (CPU Load vs. File Size)
• You can specify repeating rows and columns (from the top and left respectively), useful when printing.
• Fully supported in ASP.net and Windows Services
• Supports .net Core

Usage

See USAGE.md for instructions how to use.

Changelog

2.2.0 (2018-02-24)

• Add IgnoredErrors to a Cell, to disable Excel warnings (like "Number stored as text").
• If LargeNumberHandlingMode.StoreAsText is set on a sheet, the "Number stored as Text" warning is automatically disabled for that cell.
• Add Cell.Fill property, which allows setting the Fill of the cell, including the background color, pattern type (diagonal, crosshatch, grid, etc.) and pattern color
• Add netstandard2.0 version, on top of the existing netstandard1.3 and net45 versions.

2.1.0 (2017-09-25)

• Functional Change: Numbers with more than 11 digits are forced as Text by Default, because of a limitation in Excel. To restore the previous functionality, you can set Worksheet.LargeNumberHandlingMode to LargeNumberHandlingMode.None. You can also use Cell.IsLargeNumber to check if a given number would be affected by this.
• Functional Change: Worksheet.Populate/Worksheet.FromData now also reads properties from base classes.
• Worksheet.Populate/Worksheet.FromData accept a new argument, cacheTypeColumns which defaults to false. If set to true, then Simplexcel will cache the Reflection-based lookup of object properties. This is useful for if you have a few types that you create sheets from a lot.
• You can add [XlsxColumn] to a Property so that Worksheet.Populate/Worksheet.FromData can set the column name and a given column order. Caveat: If you set ColumnIndex on some, but not all Properties, the properties without a ColumnIndex will be on the right of the last assigned column, even if that means gaps. I recommend that you either set ColumnIndex on all properties or none.
• You can add [XlsxIgnoreColumn] to a Property so that Worksheet.Populate/Worksheet.FromData ignores it.
• Added Cell.HorizontalAlignment and Cell.VerticalAlignment to allow setting the alignment of a cell (left/center/right/justify, top/middle/bottom/justify).
• Added XmlDoc to Nuget package, so you should get Intellisense with proper comments now.

2.0.5 (2017-09-23)

• Add support for manual page breaks. Call Worksheet.InsertManualPageBreakAfterRow or Worksheet.InsertManualPageBreakAfterColumn with either the zero-based index of the row/column after which to create the break, or with a cell address (e.g., B5) to create the break below or to the left of that cell.

2.0.4 (2017-09-17)

• Support for freezing panes. Right now, this is being kept simple: call either Worksheet.FreezeTopRow or Worksheet.FreezeLeftColumn to freeze either the first row (1) or the leftmost column (A).
• If a Stream is not seekable (e.g., HttpContext.Response.OutputStream), Simplexcel automatically creates a temporary MemoryStream as an intermediate.
• Add Cell.FromObject to make Cell creation easier by guessing the correct type.
• Support DateTime cells, thanks to @mguinness and PR #16.

2.0.3 (2017-09-08)

• Add Worksheet.Populate<T> method to fill a sheet with data. Caveats: Does not loot at inherited members, doesn't look at complex types.
• Also add static Worksheet.FromData<T> method to create and populate the sheet in one.

2.0.2 (2017-06-17)

• Add additional validation when saving to a Stream. The stream must be seekable (and of course writeable), otherwise an Exception is thrown.

2.0.1 (2017-05-18)

• Fix Issue #12: Sanitizing Regex stripped out too many characters (like the Ampersand or Emojis). Note that certain Unicode characters only work on newer versions of Excel (e.g., Emojis work in Excel 2013 but not 2007 or 2010).

2.0.0 (2017-04-22)

• Re-target to .net Framework 4.5 and .NET Standard 1.3.
• No longer use System.Drawing.Color but new type Simplexcel.Color should work.
• Classes no longer use Data Contract serializer, hence no more [DataContract], [DataMember], etc. attributes.
• Remove CompressionLevel - the entire creation of the actual .xlsx file is re-done (no more dependency on System.IO.Packaging) and compression is now a simple bool.

1.0.5 (2014-01-30)

• SharedStrings are sanitized to avoid XML Errors when using Escape chars (like 0x1B).

1.0.4 (2014-01-21)

• Workbook.Save throws an InvalidOperationException if there are no sheets.

1.0.3 (2013-08-20)

• Added support for external hyperlinks.
• Made Workbooks serializable using the .net DataContractSerializer.

1.0.2 (2013-01-10)

• Initial Public Release.
