Question 1

Is my data safe? Does it ever leave my computer?

Accepted Answer

No — your data never leaves your computer. The dashboard is generated as a self-contained file with your data embedded, works 100% offline and makes zero external requests.

Question 2

What file types can I upload?

Accepted Answer

CSV and Excel (.xlsx) files are supported.

Question 3

Does my Excel or CSV file need to be cleaned up first?

Accepted Answer

Yes — your file should be reasonably clean and well-structured before you upload it. ULUTECH reads your data as-is and doesn't perform extra cleaning, so rows should have consistent columns and clear headers. Typos, misplaced values, or broken formatting in your file can carry over into the dashboard and cause it to render incorrectly. A quick check of your spreadsheet before uploading gives you the best result.

Question 4

When is a credit charged?

Accepted Answer

Only when you download a dashboard. Viewing, building and AI Generate are free — you confirm before the 1 credit is used.

Question 5

Do credits expire?

Accepted Answer

No. Credits never expire — buy once, use whenever you like. There is no subscription.

Question 6

Can I reopen and share a downloaded dashboard?

Accepted Answer

Yes. The downloaded file is a permanent, self-contained HTML — reopening, sharing and printing never cost additional credits.

Question 7

Is there a file size limit?

Accepted Answer

Yes — CSV and Excel files up to 50MB.

Question 8

Do I need an internet connection to use my dashboard?

Accepted Answer

No. The downloaded dashboard works 100% offline — your data is embedded in the file itself.
