Last updated on SEPTEMBER 07, 2021

Applies to:

Oracle Application Express (APEX) - Version 20.2 and later
Information in this document applies to any platform.

Symptoms

After Apex 20.2 upgrade downloading large reports in Excel or PDF format is very slow.

With a report that has 33,000+ rows downloaded with columns that have the leading zero, when downloading with the excel option, this report takes over 6 minutes to download.

When compared to the download speed of another report using the excel option, it took over 13 minutes. When running the CSV option for download, it downloads almost immediately or within a few seconds. When downloading a smaller report with the excel option, it downloads almost immediately or within a few minutes. Also, downloads with the data-only option selected and not selected exhibit the same download speed issue.
