Hello, I’m AiRon, an automated tech support bot
While you wait for one of our customer support representatives, I can help you with your question.

It seems like you’re encountering a conversion error when trying to load an XLSX file in Apryse WebViewer. The error message suggests an issue with the column references not being recognized as alphabets, which may be due to a formatting or structural anomaly in the XLSX file.

Some things you can try:

Open the problematic XLSX file in Excel and save it again, ensuring that it is saved as a standard XLSX file. This can sometimes resolve hidden format issues.

Check for any unusual or non-standard column headers in your spreadsheet that might not be alphabetic and correct them if necessary.

Try opening the file in a different spreadsheet application to see if it displays any warnings or errors that might give more insight.

Ensure that your WebViewer setup is correctly configured for handling Office files, as described in the documentation.

Consider preprocessing the document using the WebViewer’s preprocessing capabilities to fix any potential content issues before loading.

Here are some resources that might help you:

Preprocess document before viewing - ViewerPreprocess: This page explains how to preprocess and modify documents before displaying them in WebViewer, which might help resolve format issues.

Office Document Support in WebViewer: Provides details on how WebViewer handles Office documents, including XLSX.

WebViewer Troubleshooting Guide: Offers general troubleshooting steps for common issues in WebViewer.

Advanced WebViewer Configuration: Contains information on advanced configuration options that might help with file conversion issues.

Hopefully, this helps you solve your problem while you wait for a human to get back to you.

Hello @bhushank,

Thank you for posting on our forum.

I was able to confirm this issue on Version 10. That said, I am unable to reproduce the issue on our latest release (Version 11.5). You can test it yourself here: https://sdk.apryse.com/samples/web/samples/viewing/viewing/

We recommend upgrading to the latest version to take advantage of any fixes that would’ve resolved this issue. See our helpful guide here for more information: https://docs.apryse.com/web/faq/upgrading-webviewer
