Open a CSV.
It never leaves this tab.
Sort it, filter it, fix a cell, add a column, then save it back out. Works offline once loaded, and opens 100,000 rows without a hiccup.
- Round trip is exact. Leading zeros, quotes and line breaks inside cells come back as they went in.
- Excel-safe save. UTF-8 with a byte-order mark, so accents open correctly.
- Free try. Files up to 5,000 rows and two downloads.
Common questions (FAQ)
What does the £9.00 buy?
One payment, no subscription. It opens files of any size (the free try stops at 5,000 rows), gives unlimited downloads (the free try has two), and adds find & replace, column stats and remove duplicates.
Where is my data kept?
Only in this browser tab. Your CSV is read and saved on your own device and is never uploaded. The page only sends an anonymous page-view count, and, when you pay or press Restore, your Stripe checkout reference to our payment checker. Never any of your file.
Which browsers work?
Current Chrome, Edge, Firefox and Safari, on desktop and phone. After the first visit it also works offline.
Can I get a refund?
Access starts straight away, so the 14-day cancellation right ends once you use it. If something does not work for you, email business@thatched.ai and we will sort it out.
