About locacsv.com

Practical CSV work in your browser

locacsv.com is a free web tool for splitting, merging, encoding and JSON conversion, key-based joins, filtering, column selection, deduplication, sorting, and aggregation.

Its goal is to make common data operations approachable without requiring advanced SQL knowledge or complicated spreadsheet steps, with interfaces in five languages.

Why processing stays local

Business CSV files may contain customer names, products, amounts, and other sensitive information. CSV contents, file names, and entered values therefore remain in the browser instead of being uploaded for processing.

What the service provides

• No installation or account registration is required.
• CSV handling accounts for quotes, commas, and line breaks inside cells.
• Available file size and processing speed depend on the device and browser.

How the project improves

We continue to improve accuracy, clarity, accessibility, and performance. Keep the original file and validate results before using the output with important business data.
