unidoc / unioffice Goto Github PK

unioffice is a library for creation of Office Open XML documents (.docx, .xlsx and .pptx). Its goal is to be the most compatible and highest performance Go library for creation and editing of docx/xlsx/pptx files.

• Documents (docx) [Word]
  • Read/Write/Edit
  • Formatting
  • Images
  • Tables
  • Word to PDF (docx to pdf)
• Spreadsheets (xlsx) [Excel]
  • Read/Write/Edit
  • Cell formatting including conditional formatting
  • Cell validation (drop down combobox, rules, etc.)
  • Retrieve cell values as formatted by Excel (e.g. retrieve a date or number as displayed in Excel)
  • Formula Evaluation (100+ functions supported currently, more will be added as required)
  • Embedded Images
  • All chart types
• PowerPoint (pptx) [PowerPoint]
  • Creation from templates
  • Textboxes/shapes

There has been a great deal of interest in performance numbers for spreadsheet creation/reading lately, so here are unioffice numbers for this benchmark which creates a sheet with 30k rows, each with 100 columns.

creating 30000 rows * 100 cells took 3.92506863s
saving took 89ns
reading took 9.522383048s

Creation is fairly fast, saving is very quick due to no reflection usage, and reading is a bit slower. The downside is that the binary is large (33MB) as it contains generated structs, serialization and deserialization code for all of DOCX/XLSX/PPTX.

The OOXML specification is large and creating a friendly API to cover the entire specification is a very time consuming endeavor. This library attempts to provide an easy to use API for common use cases in creating OOXML documents while allowing users to fall back to raw document manipulation should the library's API not cover a specific use case.

The raw XML based types reside in the schema/ directory. These types are accessible from the wrapper types via a X() method that returns the raw type.

For example, the library currently doesn't have an API for setting a document background color. However it's easy to do manually via editing the CT_Background element of the document.

doc := document.New()
doc.X().Background = wordprocessingml.NewCT_Background()
doc.X().Background.ColorAttr = &wordprocessingml.ST_HexColor{}
doc.X().Background.ColorAttr.ST_HexColorRGB = color.RGB(50, 50, 50).AsRGBString()

The bash script file run_test.sh could be used to run test and update the test result (if required). This script could receive the following parameter:

• -s: Save a baseline, updates all the test result.
• -v: Run the test in verbose mode.
• t or --testname [test name]: Run a specific test name. For example -t AddImage would be running a TestAddImage test.

To run the script in dockerized environment, use the provided Makefile such as:

make docker-test

or

make docker-update-testdata

Officially we support three latest Go versions, but internally we would test the build with up to five latest Go versions in our CI runner.
