Privacy Policy

Last Updated: January 15, 2025

At MergeExcelFiles.org, your privacy is our top priority. This Privacy Policy explains what data we collect, what we do not collect, and how we protect your information when you use our free Excel tools — including our Merge Excel Files tool, Merge Cells tool, Mail Merge from Excel to Word tool, Split Excel tool, Excel to Word converter, VBA Macro Generator, Formula Fixer, Date Converter, and AI Excel Assistant.

The short version: Your Excel files never leave your device. We cannot see them, store them, or share them — because they are never sent to our servers.

1. Your Excel Files — Zero Upload Policy

How Our Tools Work

Every tool on MergeExcelFiles.org — merging Excel files, merging cells, mail merging from Excel to Word, splitting names, converting Excel to Word, generating VBA macros, fixing formulas, and converting date formats — processes your files entirely inside your web browser using client-side JavaScript.

Your Excel files are never:

Uploaded to our servers
Transmitted over the internet
Stored on any remote server
Accessible to MergeExcelFiles.org staff
Shared with any third party

This means your Excel data — including names, addresses, financial figures, employee records, healthcare information, and any other personal or confidential data — stays on your device at all times.

Why This Matters

Many online Excel tools require you to upload files to their servers for processing. This creates serious privacy risks — your data is stored on unknown servers, potentially accessed by staff, and subject to data breach risk.

MergeExcelFiles.org was built specifically to eliminate this risk. We process everything locally so you can safely use our tools with:

Financial and accounting spreadsheets
HR and employee records
Healthcare and HIPAA-sensitive data
Confidential business documents
Personal and family information

2. AI Assistant — Data Handling

Our AI Excel Assistant and VBA Macro Generator use AI to answer Excel questions, fix formulas, and generate VBA code.

When you use these AI-powered features:

Text queries (your typed questions and formula descriptions) are sent to our AI processing service to generate responses
File uploads to the AI Assistant are processed and are not permanently stored after your session ends
We do not use your queries or file contents to train AI models
Do not submit files containing sensitive personal data (Social Security Numbers, financial account numbers, medical records) through the AI chat feature

3. Analytics and Tracking

Google Analytics (GA4)

We use Google Analytics 4 to collect anonymous usage data about how visitors use MergeExcelFiles.org. This data helps us understand which tools are most used, where our visitors come from, and how to improve the site.

Any data from files you process on our site

You can opt out of Google Analytics tracking by installing the Google Analytics Opt-out Browser Add-on.

Yandex Metrica

We also use Yandex Metrica for additional analytics. Yandex Metrica collects similar anonymous usage data as described above. It does not have access to any files you process on our site.
