Frequently Asked Questions About CleanSheet AI
Which file types does CleanSheet AI accept?
CleanSheet AI accepts CSV, XLS, and XLSX files up to 1 GB. If your workbook has multiple sheets, CleanSheet AI lets you select which one to clean before processing begins.
Is my data safe with CleanSheet AI?
Yes. Files are processed through isolated encrypted workflows and CleanSheet AI never uses your data to train AI models. You review every proposed change before it is applied.
Can CleanSheet AI split first and last names automatically?
Yes. CleanSheet AI detects combined name columns and splits them into first name and last name columns with proper title casing.
Does CleanSheet AI work for HubSpot, Salesforce, or CRM imports?
Yes. CleanSheet AI normalizes emails, E.164 phone numbers, names, and duplicate records so the downloaded file is ready to import.
Is there a free plan for CleanSheet AI?
Yes. The Free plan includes 5 files per month, up to 10 rows per file, 5 AI analyses per month, and CSV/XLSX export. No credit card is required.
What if CleanSheet AI proposes a fix I do not want?
Every transformation is proposed, not applied silently. You review column suggestions before accepting them, can leave a column unchanged, and keep a full change log of applied operations.
Can I cancel my CleanSheet AI subscription?
Yes. You can cancel from the Stripe billing portal without contracts or cancellation fees. If you cancel, you keep paid access until the end of the current billing period, and paid plans include a 15-day money-back guarantee.
How does the AI analysis quota work?
Each AI analysis scans one file with Google Gemini Flash. Free includes 5 AI analyses per month, Pro includes 10, AI Basic adds 100, and AI Pro adds unlimited analyses.
Can I invite my team?
Team workspaces are not yet available as shared seats. Today, each user has an individual account, and you can invite colleagues through the referral flow while team collaboration is being developed.
Can CleanSheet AI handle files with thousands of rows?
Yes. The Pro plan supports unlimited rows per file, up to 1 GB in size. AI analysis runs column by column rather than row by row, so a 10,000-row file typically completes in under 3 minutes.
What is data normalization and why does it matter before a CRM import?
Data normalization converts values to a consistent expected format. CRMs reject or misread inconsistent formats, which causes failed imports, broken automations, and inaccurate reporting.
Who built CleanSheet AI?
CleanSheet AI was built by Revenue Hub, a team that normalizes hundreds of client spreadsheets every month for B2B companies across Latin America.
