Issue with Sheet name having more than 31 characters

Hi Aspose team,

We are encoutering one issue with assigning the sheet name at runtime.

We are fetching the sheet names from one XML and assigning. There is a chance to add some additional characters to the sheet name at runtime based on data

Here is the sample:

string sheetName = <> + (adj.Private ? " Private" : "");

But if the sheet name is exceeding more than 31 characters, we have encountered the following issue

The max length of the sheet name is 31

Please let us know by any chance aspose handle this type of situations by truncating the extra characters.

Hi Kiranmayi,

Thank you for using Aspose products.

Aspose.Cells component follows MS Excel guidelines in its implementation, therefore you cannot set the sheet name having length greater than 31 characters using Aspose.Cells (all flavors). Moreover, Aspose.Cells API does not provide any means to truncate the sheet name in case the length exceeds the specified limit, instead it throws an appropriate exception as mentioned in your message. I am afraid, you have to write you own custom routines to check the text length before setting it as a sheet name. Similarly, if the text length exceeds the limit, you have to come up with your own custom logic to truncate the text accordingly.

Please feel free to write back in case you have further questions.

Hi @babar.raza,

Apache POI provides certain feature of creating safe sheet names,I wish the same feature to be built in ASPOSE as well,if that’s seems to senseful.
