NanoXLSX.Formatting
NanoXLSX is a small .NET library written in C#, to create and read Microsoft Excel files in the XLSX format (Microsoft Excel 2007 or newer) in an easy and native way
The Formatting package is responsible to enable NanoXLSX for the handling of structured text within a text cell (inline formatting).
Currently supported:
- Adding text runs (paragraphs) by a Builder or manually
- Defining Font styles per run
- Adding phonetic information (important for East Asian languages)
- Reading and writing runs, phonetic information and inline Font styles

See the Change Log for recent updates.
What's new in version 3.x
This is the first release if this package. It was set to v 3.x, to be consistent with the NanoXLSX v3 ecosystem
Road map
Planned features:
- Style builder for general cell styles
- Assistant for valid custom format codes
- Support for conditional cell formatting
Requirements
NanoXLSX.Formatting is not intended as standalone package. It requires NanoXLSX.Core, and is normally part of the meta-package NanoXLSX
You find all technical requirements in the main repository: NanoXLSX
General requirements
- .NET 4.5 or newer / .NET Standard
- NanoXLSX.Core as only dependency
Utility dependencies
The Test project and GitHub Actions may also require dependencies like unit testing frameworks or workflow steps. However, none of these dependencies are essential to build the library. They are just utilities. The test dependencies ensure efficient unit testing and code coverage. The GitHub Actions dependencies are used for the automatization of releases and API documentation
Installation
Using NuGet
By package Manager (PM):
Install-Package NanoXLSX.Formatting
By .NET CLI:
dotnet add package NanoXLSX.Formatting
Usage
Quick Start (manual)
Workbook workbook = new Workbook("sheet1"); // Create new workbook
FormattedText formattedText = new FormattedText(); // Create new formatted text
Font strikeFont = new Font() { Strike = true }; // Create a new font style
formattedText.AddRun("strike", strikeFont); // Add text and style as run to the formatted text
formattedText.AddLineBreak(); // Add a line break after the first run
Font boldFont = new Font() { Bold = true, Name = "Tahoma" }; // Create a second font
formattedText.AddRun("bold", boldFont); // Add a second run to the formatted text
workbook.CurrentWorksheet.AddFormattedTextCell(formattedText, "A1"); // Add formatted text to the worksheet
Quick Start (builders)
Workbook workbook = new Workbook("sheet1"); // Create new workbook
InlineStyleBuilder inlineStyleBuilder = new InlineStyleBuilder() // Create a new inline style builder
.Color("FFAABBCC") // Add properties to the builder
.Italic()
.Size(18);
FormattedTextBuilder builder = new FormattedTextBuilder(); // Create a new formatted text builder
builder.AddRun("朝日", inlineStyleBuilder.Build()); // Add a text and style to the builder
builder.AddPhoneticRun("あさひ", 0, 2); // Add a phonetic run to the builder
builder.AddRun("Asahi", new Font() { VerticalAlign = Font.VerticalTextAlignValue.Superscript }); // Add another text and style to the builder
workbook.CurrentWorksheet.AddFormattedTextCell(builder.Build(), 0, 0); // Create the formatted text and add it to the cell // Save the workbook as myWorkbook.xlsx
