This Privacy Policy explains what data the Sheet2JSON app for Windows handles. The short version: Sheet2JSON converts your spreadsheets to JSON entirely on your own PC. The files you convert, their contents and the JSON they produce never leave your machine. The only thing that ever reaches a server of Bosau Digital LLC ("we", "us") is a license check. The app builds no analytics profile of you and shows no advertising. This policy covers the app; for the pythonandvba.com website itself, please see the website Privacy Policy.

1. Who We Are

Sheet2JSON is made by Bosau Digital LLC, the company behind pythonandvba.com. For any privacy-related question, contact contact@pythonandvba.com.

2. Your Spreadsheets Never Leave Your PC

Everything Sheet2JSON does to your files happens locally. The reader and converter ship inside the app and run on your computer: Excel workbooks, CSV files, LibreOffice documents and pasted cells are read and turned into JSON right there. No cloud service and no AI service ever sees your data.

The JSON, NDJSON, CSV or TSV you produce is copied to your clipboard or written only to the folders you choose when saving. Sheet2JSON does not upload, sync or transmit your spreadsheets, their file names or their contents. There is no server that could receive them.

3. Data Stored on Your PC

The app keeps a small amount of data locally, in its data folder (Excel2JSON) inside your Windows local app data folder (%LOCALAPPDATA%) and in the app's own local settings storage:

• Your license key and activation details
• Your app settings, such as the chosen output format and dark mode
• Your acceptance of the license agreement (EULA)
• The free-tier conversion counter (how many free conversions you have used), kept in the app's data folder, the Windows registry and a small hidden file in your Windows user folder

Uninstalling. Because Sheet2JSON comes from the Microsoft Store, uninstalling removes the app's data, including your saved license key; enter the key again after reinstalling. To erase your data yourself, delete the data folder. The free-tier counter is kept on purpose: its registry copy survives deleting the folder, and a small hidden file named .excel2json in your Windows user folder survives both deleting the folder and uninstalling, so the free conversions cannot be reset by reinstalling. These copies hold only the signed count, nothing about you or your spreadsheets.

4. Data That Leaves Your PC

License checks

When you enter your license key, and each time the app starts while a key is stored, Sheet2JSON verifies the key against our license server at api.pythonandvba.com. This sends your license key, the name of your PC together with a short identifier derived from your Windows installation (used to enforce the per-device limit of your license), and the app version. It never includes your spreadsheets, file names or any cell contents. If our server cannot be reached - for example while you are offline - the app simply keeps working. If our server reports that the key is no longer valid, the app removes the saved key from your PC.

Like any web server, our license server also receives your IP address with each check. It appears, with the approximate country derived from it, in our server logs, which are deleted after 14 days (90 days for warnings and errors). The device names registered to your license are kept with your license record (when each was first seen and last used) for as long as the license exists. If a check fails, we keep the license key, IP address, approximate country, device name and app version for up to 90 days to detect misuse of keys.

Nothing else

That is the complete list. On the free tier, before a license key is ever entered, the app makes no network requests at all - the free conversions are counted on your device. There is no update check (updates come through the Microsoft Store), no usage ping, no analytics, no advertising and no automatic error reporting. The Help, Documentation, Support and Changelog buttons simply open pythonandvba.com pages in your normal web browser. The account button opens our account portal in your browser; that link carries your license key so the portal knows which license you mean, and the website Privacy Policy applies there.

Support requests

Sheet2JSON has no built-in support form. If you contact us by email or through the contact form on our website, your message is handled as described in the website Privacy Policy, including the service providers that help us deliver and answer it (for the contact form: Reoon for the email check, Postmark for email delivery, Todoist for our task list, and our self-hosted customer database, FluentCRM). We keep support messages as support history for up to 24 months after your last contact, then delete them; ask us to delete them sooner.

5. Microsoft Store

Sheet2JSON is installed from the Microsoft Store, so installation and updates are handled by Microsoft, which may process install and usage statistics under its own privacy statement; we only see the aggregated numbers Microsoft shows to app publishers, never anything about you personally.

6. Purchases

Licenses are purchased on pythonandvba.com, not inside the app. Payment and billing information is processed by Pabbly Subscription Billing, Stripe and/or PayPal; we receive your email address and the product purchased in order to deliver your license key. We do not store your payment card details. Please see the Pabbly, Stripe and PayPal privacy policies for details.

7. Legal Basis for Processing (GDPR)

If you are in the European Economic Area or the United Kingdom, we process the data described above under these legal bases:

• Contract performance: validating your license and delivering the product you bought
• Legitimate interests: enforcing the per-device license limit, detecting misuse of license keys, keeping short-lived server logs to prevent abuse and diagnose faults, and answering the support messages you send
• Legal obligation: keeping transaction records where the law requires it

8. Data Sharing

We do not sell personal data. Purchase data is shared with the payment processors named above, and license records are stored by our hosting providers on our behalf. Support messages are shared only with the service providers that help us deliver and answer them (see Support requests). Nobody else receives your data, and your spreadsheets cannot be shared with anyone because they never reach us in the first place.

Bosau Digital LLC is based in the United States, so the data described in this policy is processed in the United States and/or in the countries where our service providers operate. Where personal data of EEA or UK residents is transferred internationally, we and our service providers rely on appropriate safeguards such as the EU-U.S. Data Privacy Framework and/or Standard Contractual Clauses.

9. Data Retention

• License and activation records: kept for as long as your license is active and as required by law; this includes the device names registered to your license
• Server logs: deleted after 14 days (90 days for warnings and errors)
• Failed license checks: deleted after 90 days
• Support messages: kept as support history for up to 24 months after your last contact, then deleted
• Everything on your PC: under your control alone. The app never deletes your spreadsheets or the files you saved; it removes the saved license key only when you deactivate it or our server reports the key as no longer valid

10. Your Rights

If you are in the EEA or the UK, you have the right to access, correct, delete, restrict or receive a copy of the personal data we hold about you (which is limited to license, purchase and support records), and to object to processing based on legitimate interests. Contact contact@pythonandvba.com and you will receive a response within 30 days. These requests are honoured for customers everywhere, not only where the law requires it.

You also have the right to lodge a complaint with your local data protection supervisory authority. In the UK this is the Information Commissioner's Office (ico.org.uk); in the EEA you can find your national authority through the European Data Protection Board (edpb.europa.eu). We would welcome the chance to resolve your concern first, so please consider contacting us before you do.

11. Data Security

All communication between the app and our servers uses encrypted connections. On your PC, your spreadsheets, settings and license are protected by your Windows user account like your other files.

12. Children's Privacy

Sheet2JSON is a productivity tool and is not directed at children under 16. We do not knowingly collect personal data from children.

13. Changes to This Policy

We may update this Privacy Policy from time to time. The "Last updated" date at the top reflects the latest change. Material changes will be visible here before they take effect.
