Merged pull requests:

0.11.0 (30 May 2020)

This is a feature release that enables compatibility with CryptoOffice for decrypting spreadsheets. Additionally, with 0.11.0 you can easily get worksheet names with a new parseWorksheetPathsAndNames function on XLSXFile and get rich text values from cells with a new richStringValue function on Cell.

Due to technical issues, Swift 5.0 CI job for Linux has been removed, so compatibility with Swift 5.0 on Linux can no longer be guaranteed. While CoreXLSX may continue to work with Swift 5.0 on Linux, please update to Swift 5.1 or later to avoid unexpected issues.

Thanks to @kobylyanets and @duodo2412 for their contributions to this release!

New APIs:

  • XLSXFile now provides a new initializer that takes an argument of Data type. This allows opening in-memory documents, the primary example being spreadsheets decrypted with CryptoOffice.

  • XLSXFile now has a new parseWorksheetPathsAndNames function that returns an array of worksheet names and their paths in a given workbook, while previously you had to use parseWorksheetPaths and match paths manually with results of the parseWorkbooks function.

  • Cell now has a richStringValue function that takes a result of XLSXFile.parseSharedStrings function and produces an array of RichText values. This makes it easier to query rich text content from cells, while previously you had to match cell values against SharedStrings manually.

Breaking change:

Due to the introduction of the new XLSXFile.init(data:) initializer, the filepath property on XLSXFile no longer makes sense. This property was not used internally in any way and in-memory files don't have any filepaths. If you need to refer to a filepath of an .xlsx file after you've parsed from your filesystem, you should retain it manually and process it separately as you see fit.

Closed issues:

  • API for matching sheet names to sheet paths (#105)

0.10.0 (6 April 2020)

This is a release with bugfixes and a few improvements to usability of the spreadsheet cell values API. Thanks to all contributors and users, you provide an invaluable amount of feedback and help!

New API:

The library now provides a simplified API to fetch string and date values from cells, which is much easier to use than the previous version (which is still available).

Here's how you can get all strings (including shared strings) in column "C" for example:

let sharedStrings = try file.parseSharedStrings()
let columnCStrings = worksheet.cells(atColumns: [ColumnReference("C")!])
  .compactMap { $0.stringValue(sharedStrings) }

To parse a date value from a cell, use dateValue property on the Cell type:

let columnCDates = worksheet.cells(atColumns: [ColumnReference("C")!])
  .compactMap { $0.dateValue }

Breaking change:

The type property on Cell is no longer of String type. It was previously used to check if cell's type is equal to "s", which denoted a shared string. You should use enum values for that since this release, which for shared strings now is (unsurprisingly) .sharedString.

Closed issues:

  • Xcode 11 installation and build (#90)
  • Reading Date values from cell (#89)
  • Can't open xml (#82)
  • Not able to read Numeric data from Sheet (#81)
  • Getting the value of a cell with number format? (#71)
  • Opening xlsx file Document Directory, Crashes (#52)

0.5.0 (18 April 2019)

This is a release with API additions and bug fixes.

This release of CoreXLSX can be integrated as a Swift 5 module if you're using Xcode 10.2, but support for Swift 4.2 and earlier Xcode 10 versions is also maintained.

Compatibility is improved for big files and files that internally contain namespaced XML. A few other previously reported compatibility issues are now fixed. Many thanks to everyone who reported the issues, the improvements in this release wouldn't be possible without your contribution!

Breaking changes:

Several properties on the model types became optional when there's no guarantee they are always available in files generated by different apps and tools.

Additions:

Now you can parse style information from the archive with the new parseStyles() function. Please refer to the Styles model for more details. Please note that not all XLSX files contain style information, so you should be prepared to handle the errors thrown from parseStyles() function in that case.

0.4.0 (7 February 2019)

This is a release with API improvements and bug fixes. A big thank you to everyone who provided bug reports and contributions that made this release possible!

Breaking changes:

  • A few properties on the model types were added with cleaner names and better fitting types. Most of the old versions of those properties were kept as deprecated, but you might get some breakage with optionality, where we couldn't find a good deprecation path.

Additions:

  • New parseSharedStrings function on XLSXFile allows you get values of cells with shared string value. Quite frequently those strings are unavailable and are only referenced in the original model types you get with parseWorksheet.

  • Previously when addressing cells and columns you had to use a stringly-typed API. It was also not very convenient for specifying a range of columns. This is now fixed with the new type-safe ColumnReference struct, which conforms to Comparable and Strideable.

  • Following the addition of an error context to XMLCoder, which is the main dependency of CoreXLSX, it is now exposed on struct XLSXFile. Pass a non-zero value to errorContextLength argument (default is 0) of XLSXFile initializer and you'll get a snippet of XML that failed to parse in the debug description of the error value.

  • Additional optional argument bufferSize was added to XLSXFile initializer as a response to previous reports about problems with zip file extraction. The default value is 10 MiB, which seems to be enough in most cases, but you can still try passing a larger value for bigger files if you see that an XML file stops abruptly in the middle of the file. Unfortunately, we haven't found a good way to adjust this value dynamically based on the file size, but a sufficiently large value should work for all files, which is the default.

  • Support for Carthage was added as well as support for tvOS and watchOS.

Bugfixes:

Some files that couldn't be previously parsed should now be handled better thanks to fixes in optionality and more properties added to the model types.

All changes:

0.3.0 (13 November 2018)

  • Improve Worksheet model property naming (#2). Some properties on Worksheet and its descendants had obscure names, most of that is fixed now with old names marked as deprecated.

0.2.2 (11 November 2018)

0.2.0 (11 November 2018)

  • Cell by row/column filtering API with worksheetCache (#1) This new API allows users to filter all cells by a row or column reference. To avoid re-parsing of worksheets, a new private worksheetCache property is added on XLSXFile.

0.1.2 (10 November 2018)

  • Added macOS 10.11 deployment target to the podspec

0.1.1 (10 November 2018)
