CleanSheet AI vs GPTExcel

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.

GPTExcel is a conversational web app for working with Excel and Google Sheets, with connections to CSV, MySQL, and PostgreSQL. It generates, explains, and fixes spreadsheet formulas, and can clean, reshape, split, merge, or deduplicate data with a before-and-after preview. The product also lists analysis, custom functions, and workflow automation. Work Agent handles multi-step data workflows and connects to data sources; teams can reuse saved analyses and templates. The template library contains more than 299 ready-to-use templates, and the service supports 18 languages. ChatDB runs read-only queries and cannot change connected data. Database passwords are encrypted at rest and are not returned to the browser or written to logs; files, sheets, and connections stay scoped to the account and request. The Free plan offers up to 90 credits per month through daily check-ins, and use does not require a credit card. Pro costs $19.90 per month, Max costs $29.90 per month, and API access is listed for Teams Max use cases.
