What is CSV Studio?
CSV Studio bundles the most common spreadsheet operations into one focused workspace. Use Filter to narrow rows with combined conditions (equals, contains, regex, greater-than, empty, and more). Sort by one or many columns. Bulk Update applies find-and-replace, uppercase, trim or set-value transforms to whole columns at once. Visualise draws a bar chart of any column's top values. Export the filtered view to CSV, TSV, JSON, XLSX, Markdown or HTML.
Every operation runs locally in your browser — no upload, no server, no signup.
FAQ
- How big a file can it handle?
- Comfortable with 10,000-row files. The table preview caps at 500 rows for performance, but filter / sort / export still operate on the full dataset.
- Is my data uploaded anywhere?
- No. Every operation — parse, filter, sort, update, export — runs in your browser. The file never leaves your device.
- Can I undo a Bulk Update?
- Yes — the Undo button rolls back the last bulk update. We keep the most recent 10 snapshots in memory.
