Bumps calamine from 0.37.0 to 0.38.0.

Release notes

Sourced from calamine's releases.

v0.38.0 - 2026-11-02

Added

• Added an XLSX API to read cell styles. A long requested feature.

  The new worksheet_style() method returns a StyleRange of Style values holding the font, fill, borders, alignment, number format and protection of each cell, with theme and indexed colors resolved, including tints.

  For streaming, XlsxCellReader adds the next_cell_with_style_id() method, which returns each cell value together with its style id in a single pass, and styles() to resolve the id to a Style. Formats without style support return an empty StyleRange. See also the xlsx_style_stream.rs example. [PR #653] and [PR #682].

  [PR #653]: tafia/calamine#653 [PR #682]: tafia/calamine#682

• Added workbook_properties() methods to Xls and Ods in addition to the xlsx and xlsb support in the previous release. The workbook document properties can now be read from all the supported formats, including via open_workbook_auto(). [PR #756] and [PR #757].

  [PR #756]: tafia/calamine#756 [PR #757]: tafia/calamine#757

• Added WorkbookProperties::custom_properties to read the custom, user defined, document properties as a map of property name to text value. [PR #750].

  [PR #750]: tafia/calamine#750

Fixed

• Fixed XLSX reading of packages whose main workbook part isn't named xl/workbook.xml. The part name is now read from _rels/.rels. [Issue #752] and [PR #753].

  [Issue #752]: tafia/calamine#752 [PR #753]: tafia/calamine#753

• Fixed XLSX decoding of _xHHHH_ string escapes to handle all UTF-16 code units, including surrogate pairs, instead of only _x00HH_. [PR #751] and [PR #767].

  [PR #751]: tafia/calamine#751 [PR #767]: tafia/calamine#767

• Fixed XLSB date and time formats not being applied to whole-number cell values stored as integer RK records. These were returned as Data::Int
