Hi Poorvi,
Have you troubleshooted on what level the issue exist?
In preview, when you export the Excel snapshot, do you see 150 characters?
If data is in Excel but not visible in dashboard, can you test this issue by mapping the Excel sheet cell (with 150 chars) to simple spreadsheet component with "wrap text" checked on cell and check in preview?
If data in Excel is truncated, can you use any debugging tool say Charles Debugger , etc. to check what is being fetched by QAAWS query?
Regards,
Yuvraj
