About CSVTools.pro
Practical browser-based utilities for routine CSV work.
What the site is for
CSVTools.pro is a collection of focused tools for tasks that regularly arise when moving data between spreadsheets, CRMs, ecommerce platforms and other systems. You can split or merge files, inspect rows, remove duplicates, select columns, change delimiters and convert between CSV and JSON.
The aim is straightforward: make common data preparation jobs accessible without requiring an account or a software installation. Each tool is kept separate so its purpose and output are clear.
Privacy by design
File processing takes place in your web browser. The selected file's contents are not uploaded to the CSVTools.pro server for processing. This matters for business exports and personal data, and avoids an unnecessary copy being sent elsewhere merely to complete a simple conversion.
The website does not currently load analytics or advertising scripts. Any future use of those services will be described in the Privacy Policy.
Useful, verifiable results
Data tools should not encourage blind trust. Preview important results, retain an original copy and validate row counts, headers and sample records before importing an output file into another system. Browser-based processing also depends on the memory available on your own device, particularly for very large files.
