CleanSheet AI vs ExcelAI

CleanSheet AI is a standalone web tool for cleaning and normalizing CSV, XLS, and XLSX files without formulas. Users upload a file, choose a sheet when a workbook has several, review suggested changes, approve fixes, and download the result. It can split names, standardize dates and currencies, correct email formatting, format phone numbers, and detect duplicates. Files can be up to 1 GB, and approved operations appear in a change log. The maker says cleaned files can be prepared for HubSpot, Salesforce, and CRM imports. Processing uses isolated encrypted workflows, files are not used to train AI models, and data is isolated by account. Free support is by email; Pro includes priority support. The Free plan costs nothing and allows five files monthly, ten rows per file, and five AI analyses. Pro costs $15 a month.

ExcelAI is an add-in that works inside Microsoft Excel and handles natural-language requests. It can write formulas, generate P&L statements, balance sheets and cash flow reports, format sheets, create charts, clean data and run multi-step workflows with undo support. Its analysis can identify patterns and anomalies and process thousands of rows, according to the maker. ExcelAI is a COM add-in for Excel 2019, Excel 2021 and Microsoft 365 on Windows and macOS. Listed model providers include Claude, GPT-4o, Gemini, DeepSeek, Llama and Mistral. The privacy policy says prompts and temporary operation context are processed transiently, while the maker says it does not store workbook contents or train AI models on user data. Communications with its servers are encrypted using TLS 1.3. A free plan includes 20 requests per five hours. Starter is listed at $5 a month for the first month, then $10/month; Pro is listed at $20 a month, with billing details stating no monthly fee and a separate $0.88 card processing fee. Google Sheets is marked as coming soon.
