As answered by people managing CSVTool.io and SmoothCSV.
SmoothCSV's answer:
SmoothCSV tries to make CSV editing feel familiar: grid editing like Excel, keyboard-first workflows like VS Code, and careful preservation of details like encoding, delimiter, and original quoting. It also handles messy files with inconsistent column counts, and lets you run SQL queries directly on CSV data.
SmoothCSV's answer:
Every feature is free to use, and it runs on Windows, macOS, and Linux. It keeps your file's format as it is when saving, including the original quoting, which many editors drop. It also brings SQL queries, multi-cell editing, and side-by-side CSV comparison into one app, and it gets regular updates.
SmoothCSV's answer:
Tauri, Rust, TypeScript.
SmoothCSV's answer:
Anyone who works with CSV files: software developers, data analysts, and people who need to check or fix CSV files without a spreadsheet app changing their data.
SmoothCSV's answer:
I've been building CSV editors since 2011. Spreadsheet apps kept reformatting my data (dates, leading zeros, long numbers), and text editors kept the data safe but lost the grid view, so I wanted a dedicated tool that does both. The current version is my third rewrite from scratch, started in 2024 and released in 2025.
