Document format · .csv
CSV (comma-separated values) is the simplest tabular format: rows of values that open in Excel, Google Sheets, databases, and data tools everywhere. It is the pragmatic bridge between spreadsheets and code — convert it to JSON for APIs or clean it up for analysis.
Every tool runs in your browser — files never leave your device. Badges say exactly what each tool does with CSV.
The CSV splitter divides by row count or chunk size locally — no upload, so even multi-megabyte exports process fast in your browser.
Excel expects a UTF-8 BOM marker and your locale's delimiter (often semicolons in Europe). Re-save with BOM or switch delimiters before opening.
Yes — the CSV merger stacks files with matching columns into a single download, all locally.
Never. Sorting, merging, and converting run in your browser, which matters for customer and financial data.
