Open-ended survey analysis FAQs
What to know before uploading an Excel or CSV file for sentiment classification.
What file types can I upload?
The analyzer accepts standard XLSX workbooks and CSV files up to 10 MB and 1,000 data rows. XLS, XLSM, Google Sheets links, and password-protected workbooks are not supported.
Where does the sentiment column appear?
The tool adds a new Sentiment column immediately after the last existing column. For XLSX files, it updates only the worksheet you select and leaves the other worksheets in place.
Which sentiment labels does the tool use?
Each non-empty response is classified as Positive, Neutral, Negative, or Mixed. Empty cells remain empty in the finished file.
How long are uploaded survey files stored?
Your original upload and temporary processing files are deleted as soon as the analysis finishes or fails. Only the analyzed result and a minimal status record remain available for seven days, after which they are automatically deleted. The delivery email address is removed immediately after processing.
Can I use the analyzer for protected health information?
Do not upload protected health information or other regulated sensitive data to this free public tool. Remove names, email addresses, account numbers, and other identifying details before uploading.
