Questions, answered.
The quick version of how SheetSweep handles your files.
Is my file uploaded to your servers?
No. Everything runs in your browser, so your file never leaves your device.
What files can I use?
CSV, TSV, XLSX, and XLS files work across the spreadsheet tools. The converter also accepts JSON. Free-tier files can be up to 4 MB each.
Do I need an account?
No. There’s no signup and no email required.
Does the cleaner change my original file?
No. It makes a cleaned copy for you to download. Your original stays untouched.
What happens to formulas?
They’re flagged for your review and neutralized as text. They’re never executed.
What’s the difference between Free and Pro?
Free includes the cleaner, converter, and validator for files up to 4 MB, with no signup and unlimited use. Pro adds 25 MB files, Merge, Split, Compare, and bulk workflows.
What’s the refund policy?
7-day money-back, no questions asked. Email support@sheetsweep.com and we’ll sort it.
How do I cancel my subscription?
Pro customers can open Pricing and choose Manage subscription to cancel in Stripe. If the portal does not open, email support@sheetsweep.com.
How do I get Pro?
Go to Pricing, click the Pro button, and check out. Pro is $29/month, or the $99 one-time Founder tier is available to the first 100 customers.
What counts toward the 4 MB limit?
The size of the file you upload.
Will it work on my phone?
Yes. SheetSweep works in phone, tablet, and desktop browsers.
About SheetSweep
Spreadsheet tools that stay in your browser
SheetSweep is a focused set of tools for cleaning, converting, validating, merging, splitting, and comparing spreadsheets. Everything runs entirely in your browser.
I’m Nos, the solo builder behind it. I made SheetSweep because I was tired of spreadsheet tools that upload your files to their servers or force you to create an account before doing simple work.
Why SheetSweep exists
Spreadsheet work should be direct: choose a file, do the job, and take the result.
Built for real spreadsheet work
The tools handle CSV, TSV, XLSX, and XLS files, with JSON support in the converter.
Made by one person
SheetSweep is designed and maintained by Nos, a solo builder focused on useful, straightforward tools.
No upload. No signup.
Your spreadsheets never leave your browser tab, and you do not need an account to use the free tools.
