Hi all
When I export vizlib pivot table as formatted data to excel the data size is about 151 mb
The same pivot table when I do "Fast export pivot table to excel" the size is 1.9 mb
please can anyone help me to understand why the size difference is huge
Secondly, when I open 151mb formatted file and save as different name the file size becomes 2.3 mb, the size reduces drastically also there is no difference in table appearance
Thanks
The available libraries for Excel imports/exports for any third-party-tools aren't the same as Excel as desktop tool. Differences might be occur in the way the compression is performed (a xlsx is only a zip-container for multiple xml-files) or if any data store-optimization could be applied.
Personally, I wouldn't be surprised if the export is done seriell cell for cell and assigning for each the format-information within an own xml-branch. To conclude if a whole column or even the entire table has the same format and could be therefore much more efficient addressed with a cell-range needs an extra evaluation - in beforehand or afterwards - which is probably above the technically and/or licencing possibilities respectively beyond the main-aim of the export - just exchanging data.
