This does not cover the entire ODS spec.

What is supported:

• Spread-sheets

  • Handles all datatypes
    • Uses time::Duration
    • Uses chrono::NaiveDate and NaiveDateTime
    • Supports rust_decimal::Decimal
  • Column/Row/Cell styles
  • Formulas
    • Only as strings, but support functions for cell/range references.
  • Row/Column spans
  • Header rows/columns, print ranges
  • Formatted text as xml text.

• Formulas

  • Only as strings.
  • Utilities for cell/range references.

• Styles

  • Default styles per data type.
  • Preserves all style attributes.
  • Table, row, column, cell, paragraph and text styles.
  • Stylemaps (basic support)
  • Support for setting most style attributes.

• Value formatting

  • The whole set is available.
  • Utility functions for common formats.

• Fonts

  • Preserves all font attributes.
  • Basic support for setting this stuff.

• Page layouts

  • Style attributes
  • Header/footer content as XML text.

• Cell/range references

  • Parsing and formatting

What is not supported:

• Spreadsheets
  • Row and column grouping
• …

There are a number of features that are not parsed completely, but which are stored as a XML structure. This might work as long as these features don’t refer to data that is no longer valid after some modification. But they are written back to the ods.

Anyway those are:

• tracked-changes
• variable-decls
• sequence-decls
• user-field-decls
• dde-connection-decls
• calculation-settings
• content-validations
• label-ranges
• named-expressions
• database-ranges
• data-pilot-tables
• consolidation
• dde-links
• table:desc
• table-source
• dde-source
• scenario
• forms
• shapes
• calcext:conditional-formats

When storing a previously read ODS file, all the contained files are copied to the new file, except styles.xml and content.xml. For a new ODS file mimetype, manifest, manifest.rdf, meta.xml are filled with minimal defaults. There is no way to set these for now.

Modules

defaultstyles
error
format	Defines ValueFormat for formatting related issues
formula	For now defines functions to create cell references for formulas.
refs	Defines types for cell references.
style	Styles define a large number of attributes. These are grouped together as table, row, column, cell, paragraph and text attributes.
text	Text is stored as a simple String whenever possible. When there is a more complex structure, a TextTag is constructed which mirrors the Xml tree structure.
xmltree	Defines an XML-Tree. This is used for parts of the spreadsheet that are not destructured in detail, but simply passed through. With a little bit of luck there is still some meaning left after modifying the rest.

Macros

cm	Centimeters.
currency	currency value
deg	deg angles. 360°
em	Length depending on font size.
grad	grad angles. 400°
inch	Inches.
mm	Millimeters.
pc	Pica. 12/72“
percent	currency value
pt	Point. 1/72“
rad	radians angle.

Structs

CellStyle	Describes the style information for a cell.
CellStyleRef	Refers to a $l.
SCell	One Cell of the spreadsheet.
Sheet	One sheet of the spreadsheet.
WorkBook	Book is the main structure for the Spreadsheet.

Enums

Value	Content-Values
ValueType	Datatypes
Visibility	Visibility of a column or row.

Functions

read_ods	Reads an ODS-file.
write_ods	Writes the ODS file.

Type Definitions

ucell

Cell index type for row/column indexes.
