CSV Encoding Importer — a Google Sheets™ add-on
Effective date: July 3, 2026

1. Overview

CSV Encoding Importer (the "Add-on") is a Google Sheets editor add-on developed and operated by Minseong Kim (the "Developer", "we") that imports CSV files with automatic character-encoding detection and exports sheet data as CSV files in an encoding of your choice.

The Add-on is designed around a simple principle: your data never leaves your browser and your Google account. It has no external servers, no databases, and collects no personal information.

2. Information the Add-on Accesses

The Add-on requests the minimum Google OAuth scopes necessary to function:

ScopePurpose
https://www.googleapis.com/auth/spreadsheets.currentonly Read and write access only to the spreadsheet in which you run the Add-on. Used to write imported CSV rows into the sheet and to read displayed cell values when exporting. The Add-on cannot see any of your other spreadsheets or Drive files.
https://www.googleapis.com/auth/script.container.ui Display the Add-on's sidebar user interface inside Google Sheets.

CSV files you select for import are read locally inside the Add-on's sidebar in your browser. Encoding detection, decoding, and CSV parsing all happen in your browser. Only the resulting parsed cell text is transferred — via Google's own Apps Script infrastructure — into your spreadsheet. File contents are never transmitted to the Developer or to any third party.

CSV files you export are generated entirely inside your browser and delivered as a direct browser download. Nothing is uploaded anywhere.

3. What We Do NOT Do

4. Data Storage and Retention

The Developer stores nothing. During an import, the Add-on keeps small technical markers (import progress positions used to prevent duplicate writes if a network retry occurs) in Google Apps Script's cache service. These markers are tied to your spreadsheet, contain no file contents, and expire automatically within approximately one hour.

5. Google API Services User Data Policy

CSV Encoding Importer's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

6. Revoking Access

You can revoke the Add-on's access to your Google account at any time:

  1. Visit Google Account – Third-party apps & services, or
  2. Uninstall the Add-on from Google Sheets (Extensions → Add-ons → Manage add-ons).

Because the Add-on stores no data, revoking access removes everything immediately.

7. Children's Privacy

The Add-on is not directed at children and, in any case, does not collect personal information from anyone.

8. Changes to This Policy

If this policy changes, the updated version will be posted at this page with a revised effective date. Material changes will be reflected before they take effect.
