Excel Tools

It's deprecated, but it's still included and still works, as of the last I checked.

Hi

Using Merge Excel documents has been working very successfully. Now shows an error -

Merge Excel Documents A part with the name '/docProps/core.xml' already exists : Packages shall not contain equivalent part names and package implementers shall neither create nor recognize packages with equivalent part names. [M1.12].

Any ideas as to cause and how to overcome this error?

Regards

Hello Mike 

we are trying to read an excel file but we get this error.

ERROR com.appiancorp.ps.exceltools.util.ExcelHelperUtils - Zip bomb detected! The file would exceed the max. ratio of compressed file size to the size of the expanded data.
This may indicate that the file is used to inflate memory usage and thus could pose a security risk.
You can adjust this limit via ZipSecureFile.setMinInflateRatio() if you need to work with files which exceed this limit.

We get this error using all the 3 function available with the plug in

• Read Excel File Paged
• Read Excel Cell by Name
• Read Excel Cell by Number

This error occur with the latest apache poi when in the excel file there are many rows/columns with the same content, and in my excel file i have this issue.

could be possible to set: 

ZipSecureFile.setMinInflateRatio(0); in oprder to avoid this error or some other fixing.

Let me know if you need an exemple of my excel to read.

Thank You

Gianluca

Hi Mike ,

We facing the below error message , while uploading the excel file.

below is the formula we are having for one column

=IF(COUNTBLANK(B3:H3)=7,"-",IF(B3="","Subprocess,","")&IF(IFERROR(XLOOKUP(TRUE,EXACT(B3,'Manual Reporting Actions'!$B$1:$B$10),
'Manual Reporting Actions'!$B$1:$B$10,1),1)=1,"SubProcess,","")&IF(IFERROR(XLOOKUP(TRUE,EXACT(C3,'Manual Reporting Actions'!$C$1:$C$10),
'Manual Reporting Actions'!$C$1:$C$10,1),1)=1,"Action,","")&IF(XLOOKUP(C3,'Manual Reporting Actions'!$C$1:$C$10,'Manual
Reporting Actions'!$B$1:$B$10,",SubProcess not matched with Action,",0)=wft_manal_reporting_details!B3,"",",
Subprocess Not Matched with Action")&IF(D3="","Company,","")&IF(IFERROR(XLOOKUP(TRUE,EXACT(D3,'Manual Reporting Actions'!$E$1:$E$10),

IF(AND((F3>=IF(TEXT(TODAY(),"DD")>=6,EOMONTH(TODAY(),-1)+1,EOMONTH(TODAY(),-2)+1)),(F3<=IF(TEXT(TODAY(),"DD")>6,
TODAY(),DATE(TEXT(TODAY(),"YYY"),TEXT(TODAY(),"MM"),6)))),"","Start Date,")&IFERROR(IF(ISNUMBER(MONTH(G3)),"","End Date,"),"End Date,")
&IFERROR(IF(AND(F3<=G3,G3<=TODAY()),"","End Date,"),"End Date,")&IF(AND((F3>=EOMONTH(TODAY(),-2)+1)),"",
"Start Date,")&IF(AND((G3>=EOMONTH(TODAY(),-2)+1)),"","End Date,")&IF(ISNUMBER(H3),"",",TotalVolume"))

from the logs we came to know that XLOOKUP is not supported by this plugin, check the below logs.

Hi Mike. Looks like any errors during the Import Excel to Database smartservice leave a hung database connection?

If my file generates an error I can't get back to the cloud DB until it times out sometime later...

log4j is not bundled in the plugin - it uses the lib packaged in the base product.
