2023.8.31 - August 31st, 2023
We present to your attention a completely new engine
of Excel to PDF .Net 2023.8!
Let's see what's new:
We have added support for the XLSX format.
Now our component complies with all modern document management
requirements.
XLSX files are the standard extension for the modern Microsoft
Excel spreadsheet files. They are a zip-compressed XML
spreadsheet file used to analyze and organize data. They contain
numerical data separated by rows and columns within a cell. It
is a modern, updated version of the original Excel file format.
Improved "XSLX to PDF" conversion speed by 3 times.
Improved "XSLX to DOCX" conversion speed by 2 times.
Improved "XLSX to RTF" conversion speed by 4 times.
Added support for multiple versions of PDF format: PDF 1.2 — 1.7, PDF/A-1a — PDF/A-3u. https://en.wikipedia.org/wiki/PDF/A.
Improves performance when reading any of the Range object's properties, especially in case of large Ranges. This applies to all objects that are inherited from Range (WorkSheet, RangeRow etc.)
Reworked interfaces for interaction between XLSX — PDF, DOCX, RTF. But they left the obverse compatible with older versions. This will allow old customers to easily migrate to the new engine.
Fixes some other rare bugs that occasionally might result in a corrupted file.
.NET 8.X: Improved speed and stability of the dll with the operation into memory.
Fixes a bug where files containing pivot tables were loaded through Excel to PDF .Net then saved and resulting files come out corrupted.
Greatly improves performance, generating a PDF file with 10000 used cells used to take up 65 seconds takes only 18 seconds (will vary depending on operations performed on a cell by your code).
