Privacy
SheetShift is designed around local browser processing. CSV, TSV, or JSON data you paste or choose is not uploaded to our servers or written to long-term site storage.
Your data follows three steps
Read and parse
Browser FileReader reads files locally; delimiter detection and JSON parsing run on this page.
Inspect and clean
Search, sort, hidden columns, blanks, and duplicate counts exist only in current page memory.
Choose to export
Only your click writes results to the clipboard or creates CSV, TSV, or JSON downloads.
Current page memory
Input data, parsed rows and columns, quality profiles, search terms, sorting, and column visibility are held in this page's JavaScript memory. Clear, refresh, or close the page to remove them; SheetShift cannot view or recover them. The homepage demo uses built-in fictional data.
Clipboard and three download types
‘Copy result’ writes current content to the system clipboard and does not read it. A regular download saves the complete current data; ‘Download visible rows’ includes only filtered rows and selected columns; the quality report contains generation time, format, row/column counts, blanks, duplicates, and field completeness—not cell values. All files are generated locally and are not automatically sent back.
Local preferences and favorites
Language, theme, and high-contrast preferences are stored in your browser. These display preferences and up to 16 favorite tool IDs also use .miluland.com domain cookies so same-domain pages stay consistent. Favorites never contain inputs, files, or results, can be cleared from the MiluLand tool directory, and are not intentionally uploaded.
Advertising and third parties
This site uses Google AdSense Auto Ads. Depending on your consent, Google may use cookies or similar technologies to serve and measure ads. You can manage these choices in Google's privacy settings.
Contact
This tool is maintained by MiluLand. To report a privacy issue, use the contact page and do not paste customer lists, account data, or other private records into your message.
Optional analytics
This site loads Google Analytics only after your explicit permission to measure visits to tool and information pages. File names, file contents, tool inputs, search terms, QR payloads, URL parameters, and results are excluded. Google's enhanced measurement is off.
Your choice is saved in a .miluland.com cookie for 180 days and shared by MiluLand pages with analytics enabled. Use ‘Analytics choices’ at the bottom of the page to decline or withdraw permission; withdrawal disables measurement and clears accessible GA cookies. Browser GPC and Do Not Track keep analytics off. Advertising has separate Google consent settings.
