OkCSV by BrainyDreamer is a browser-based CSV data cleaning SaaS designed to help users avoid manually cleaning data in Excel. It requires no installation and no coding, making it suitable for quickly turning messy CSV files into datasets that are ready for analysis, import, or reporting.
The product focuses on CSV cleaning. It supports uploading single or multiple files and performing operations such as removing duplicates, trimming whitespace, standardizing dates, filtering rows, selecting columns, renaming headers, normalizing column names, filling missing values, and converting data types. It also highlights its ability to handle large files, with automatic detection of encodings and delimiters, covering encodings such as UTF-8, Latin-1, and Windows-1252, as well as delimiters including commas, semicolons, tabs, and pipes. The Premium plan supports batch processing of hundreds of files and allows different rules to be set for different files.
Pricing is straightforward: the free plan is free forever, requires no credit card, and is limited to 1 file at a time, up to 1MB, 10,000 rows, and 20 columns, while still including all cleaning features. Premium costs $9/month and supports unlimited files, 100MB+ files, unlimited rows and columns, batch processing, per-file overrides, and priority support. The terms state that subscriptions can be billed monthly or annually, are paid via Stripe, renew automatically, can be canceled at any time, and are eligible for a refund request within 7 days after payment. Deployment is via a cloud-based web app that runs in the browser and supports Windows, Mac, and Linux. Self-hosting is not mentioned.
On security, the official materials state that uploaded files are processed in real time and CSV contents are not stored permanently. Data disappears after processing is complete or when the browser is closed, and users retain ownership of their data. Payments are handled by Stripe. However, the text does not disclose certifications such as SOC 2, ISO 27001, or GDPR, nor does it describe enterprise-grade encryption, audit logs, or data residency options. For collaboration, it only mentions account registration and users’ responsibility for account security; features such as team workspaces or role-based permissions are not evident. Third-party integrations, APIs, SDKs, and webhooks are also not disclosed.
Its strengths are simplicity, low pricing, a usable free plan, and a comprehensive set of common CSV cleaning capabilities. It is especially suitable for data analysts, researchers, ecommerce operators, marketing teams, and developers working with customer lists, survey data, product catalogs, order exports, or API exports. Its limitations are the relatively narrow file format support and the lack of enterprise collaboration, compliance, integration, and automation capabilities, making it unsuitable as a large-scale data governance platform.
Access from China is not covered in the available text. Payments rely on Stripe, so users in mainland China may need to check whether international card payments are available to them. If localized support or private deployment is required, alternatives such as Excel Power Query, OpenRefine, or domestic data governance, ETL, and BI platforms may be worth considering.
