ChatGPT + Data Alias: Analyse protected data in ChatGPT, then restore the real names
Why use ChatGPT with Data Alias
ChatGPT is good at finding themes in tickets, survey answers and exports — exactly the files you can't upload as they are. Data Alias replaces names, emails and IDs with consistent aliases first, so the analysis still holds together and the identities stay with you.
How it works
There is no connection between Data Alias and ChatGPT. You protect the file in your browser, download the safe copy and the instructions prepared for AI, and upload them to ChatGPT yourself. When the answer refers to aliases such as PERSON_001, paste it into Restore and the real values come back — in your tab, from a mapping that never left it.
What it does
- Prepare a safe copy and instructions that ask ChatGPT to keep aliases exactly as written
- Keep aliases consistent, so the same person is the same alias in every row
- Swap the aliases in ChatGPT's answer back to real values, in your browser
- Warn you before download if a detected value would stay unprotected
How to use it
- 1
Protect the file
Upload a CSV, XLSX, TXT, JSON, PDF or DOCX file, or paste text. Review the suggested protection and change anything you disagree with.
- 2
Download the files for AI
Take the safe copy and the instructions. The alias mapping is not part of them.
- 3
Upload them to ChatGPT yourself
Attach both in a ChatGPT conversation and ask your question.
- 4
Paste the answer into Restore
Aliases in the answer are replaced with the real values in this tab. Read the restored answer before you use it.
What moves where
- What reaches Data Alias servers
- Nothing from the file.
- What reaches ChatGPT
- Only what you upload yourself: the safe copy and the instructions.
- What stays in your browser
- The original file, the alias mapping, and the restored answer.
- Permission you grant
- None. There is no account link.
Limits worth knowing
- Aliases replace the identifiers Data Alias detects and the columns you choose. Detection can miss a value, so review the safe copy before you upload it.
- Restore can only put back aliases that appear in the answer as written. If ChatGPT rewords or drops one, that value is not restored.
Does Data Alias send my data to ChatGPT?
No. Data Alias doesn't call ChatGPT or any other AI service. You upload the safe copy yourself.
Is the safe copy anonymous?
No. It is pseudonymised: identifiers are replaced with consistent aliases so the data stays useful. That reduces exposure, but no detector finds every sensitive value — review before you upload.
Where is the mapping between aliases and real values?
In your browser tab, and in a mapping file only if you choose to download one. It is never part of the files prepared for AI.
Data Alias reduces exposure risk but cannot guarantee detection of every sensitive value. Every transfer passes the same review as a download — check the result before you send it. How connected services are handled.
