Aspose.Cell .Xlsx Issues with Large Data in the Sheet

Aspose.Cells Product Family
1

Hi ,<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

We recently migrated our code base for Aspose.Cells from xls to Xlsx format, Since then we are experiencing some vivid issues.

The formula’s are basic such as VLookUp and If Case in the sheet. The version of Aspose.Cells.dll is 7.2.2.0.

We also tried with 7.3.3.1 version but experiencing same problem.

Below is the description of the issues:

1) For a large data . xlsx file, the Workbook.Save(“file Name”, SaveFormat.Xlsx) method time out occurs. Here we are exporting data for 16380 columns and 10 rows

For replicating the same issue, please refer the attached Aspose_POC.zip.

2) In one particular scenario, if we try to calculate the Workbook Formula’s using Workbook.Calculate() (10000 columns and 10 rows).

Same set of logic works fine for a smaller set of Data(8200 Column and 7 Rows)

· This method throws an internal exception such as the formula in a Cell is incorrect.

Error Description:

"Index was out of range. Must be non-negative and less than the size of the collection.\r\nParameter name

: index\nError in calculating cell DLD24 in Worksheet XYZ"}

System.ApplicationException {Aspose.Cells.CellsException}

For more details please refer the attached file i.e. Aspose_Error_IndexOutOfRange.png.

· If we set this formula to null, then we are able to further save this file. But the

Formula’s appearing after the error cell are altered and are pointing to different cell’s.

· One more thing if we again generate the same excel but this time bypass the Workbook.Calculate() Method and then try to Save the Workbook in Memory Stream. Then also an internal error occurs.

For more details please refer the attached file i.e. Aspose_Error_Save.png.

Hi,


Thanks for providing us the sample project and screen shots with details for your issues.

I can see the performance issue. Since you are filling huge list of formulas to be calculated that may be expanded to more than 10K columns, it would surely demand more RAM or the process might result in time out. We have look into your mentioned issues if we can fix the issues and enhance the performance more.

We have logged a ticket with an id: CELLSNET-41168 for your issue(s). We will look into them to figure out them (if possible) soon.

By the way, could you try our latest fix/version: Aspose.Cells for .NET v7.3.3.2
and add a line of code to your code segment if it makes any difference e.g

try
{
wb.Settings.CreateCalcChain = false;

<o:p></o:p>

wb_Test.CalculateFormula();
}

Thank you.

Hi,<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

In the scenario 2 mentioned in my first post.

If we try to calculate the Workbook Formula’s using Workbook.Calculate() (10000 columns and 10 rows).

Same set of logic works fine for a smaller set of Data(8200 Column and 7 Rows)

· This method throws an internal exception such as the formula in a Cell is incorrect.

Error Description:

"Index was out of range. Must be non-negative and less than the size of the collection.\r\nParameter name

: index\nError in calculating cell DLD24 in Worksheet XYZ"}

System.ApplicationException {Aspose.Cells.CellsException}

For more details please refer the attached file i.e. Aspose_Error_IndexOutOfRange.png.

We tried using new version(7.3.3.2) of dll and the changes suggested by you.It still give me the error as

"Index was out of range. Must be non-negative and less than the size of the collection.”

The only difference is that now the error message doesn't show cell number.

We also tried transposing our sheet, so now my worksheet has 10000 rows and 10 columns(including few header columns), and we have formulas on every cell. Still it gives me the same error.

"Index was out of range. Must be non-negative and less than the size of the collection.\r\nParameter name

: index\nError in calculating cell W1243 in Worksheet XYZ"} System.ApplicationException {Aspose.Cells.CellsException}

Question: Is there any defined limitation on number of formula cells in a sheet when we use Aspose.Cells ? The total number for formula cells in my worksheet is 91,665.

Please assist, I need to create a worksheet with this or more number of formulas.

Hi,

The changes suggested above, you have created only one Validation Object and applied it over the rest of the Sheet.

But these changes won't be applicable to our business scenario. Since each Cell in the worksheet could refer to a different set of Validation Rule(ie. a Date Validation, Percent Validation ,Numeric Validation etc).

Moreover, We tried to cut down the number of validations on the cells or even removed all validations from the Worksheet , still the issue#2 persists.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

For further analysis of the problem at your end, we are attaching a sample file(Test Workbook.Xlsx).

We are able to generate the Workbook similar to the Sample file, but when we increase either the number of Columns or number of rows or both (programmatically), we are unable to Save or even use CalculateFormula() method in the Code(As mentioned in the Initial Thread).

Hi,


Thanks for your feedback and sharing the sample file.

We have logged it against your existing issue “CELLSNET-41168” in our database.

We will look into it further, once we have any feedback, we will let you know here.

Thank you.

Hi Team,

Any progress made on the “CELLSNET-41168” related issues ?
Please Let us know, if any other information is required from our side.

Hi,

Thanks for your posting and using Aspose.Cells.

Please use the code as we have given in the previous post.

You must not call the Workbook.CalculateFormula() in the loop.

Hi,

In response of the thread 424492, we clearly mentioned that the code changes suggested does not suffice our business scenario.
"The changes suggested above, you have created only one Validation Object and applied it over the rest of the Sheet.

Moreover, We tried to cut down the number of validations on the cells or even removed all validations from the Worksheet , still the issue#2 persists."

As already discussed in the thread, In our actual scenario we have commented the
// Workbook.CalculateFormula() Method,

and used the below mentioned flags

wb.Settings.CreateCalcChain = false;
wb.Settings.ReCalculateOnSave = false;

and tried to Save the Workbook. Then also the same error occurs i.e.
"Index was out of range. Must be non-negative and less than the size of the collection.\r\nParameter name : index\nError in calculating cell DLD24 in Worksheet XYZ"}

Hi,

Thanks for your posting and using Aspose.Cells for .NET.

We are unable to investigate your issue properly. Could you please post your latest project here to look into this issue further?

You might also remove the code workbook.CalculateFormula(), save the workbook to xlsx file and post it here. It could also be helpful in investigating this issue.
