Changelog

Sourced from xlsxwriter's changelog.

Release 3.3.1 - October 28 2026

• Fixed performance issue where positioning objects such as images and comments on a worksheet with a custom default row height.

  :issue:1210.

• Fixed a (different) performance issue where positioning a large number of objects such as comments on a worksheet with custom row heights or column widths.

  :issue:1217.

• Fixed off by one error in the worksheet :func:set_first_sheet() method.

  :issue:1187.

• Fixed issue where :func:autofit() hid a column that had a user defined width narrower than the autofit width.

  :issue:1219.

• Fixed issue where :func:add_table() didn't detect a duplicate header name when a user defined header matched a default ColumnN header.

  :issue:1215.

• Fixed issue where the strings_to_formulas Workbook option didn't prevent :func:write() from converting strings like {=SUM(A1:B1*A2:B2)} to array formulas.

  :issue:1212.

• Fixed :func:set_column() rounding a half-pixel width to the nearest even pixel, which made some widths one pixel narrower than in 3.2.9.

  :issue:1221.

• Fixed unescaped double quotes, and incorrect string lengths for characters such as emojis, in text type conditional formats.

  :issue:1206.

• Fixed issue where "future" functions such as ISFORMULA() weren't prefixed with _xlfn. in :func:conditional_format() and :func:data_validation() formulas. See :ref:formula_future.

  :issue:1171.
