Every column knows what it is.
Text, money, dates, options, checkboxes, email, URLs and long text. The grid edits the type, not the string.
View, edit and create CSV files.
Typed columns, stacked filters, instant search and a real record form — for the file already on your desk. Save straight back to the same CSV.

One file.
One file.
No copies.
CSVita opens the CSV where it lives and writes back to that same file. There is no import step, no workspace to migrate into, and no second version to keep in sync.

Open it where it lives — drag it in or pick it from disk.

Save rewrites the same CSV, in place.

No account, no upload, no cloud copy.

The grid
A spreadsheet, with a memory.
The grid keeps the speed of a spreadsheet and adds what it never had: named fields, real types, rules you can see, and a file that stays a file.
Rules that stack.
Build a WHERE bar from real conditions. Every rule carries a count; clear one and the file comes back exactly as it was.
Type once. See everything.
Search every cell as you type. Clear it and the rows return exactly as they were — no refresh, no re-import.
Everyday work
Small surface.
Open the grid
Small surface.
Serious grid.
The parts you use every day, built to stay out of the way.
Open in place
Point it at a CSV already on disk. Nothing is imported and nothing is copied — the file is the database, and Save writes back into the same file.
Million-row scrolling
The grid renders a bounded window of rows, not the whole file, so scrolling stays instant whether the CSV holds a hundred rows or a million.
DuckDB underneath
Sort, filter, search and group are pushed into an embedded DuckDB engine instead of being evaluated over what happens to be on screen.
Typed columns
Numbers, currency, dates, select pills, checkboxes, links and long text each render as themselves, from one column editor.
Filters that stack
A WHERE bar with real conditions, a count on every rule, and one Clear all that puts the file back.
Group without pivoting
Collapse by any field. Each group counts its rows and opens back into the same sheet.
Edit, then Save
Change a cell inline or open the whole row as a form built from the columns. Cell edits are staged until you save; row operations take effect straight away, and Save & add another keeps the rhythm.
Safe writes
Saves are atomic, a stale-file check runs before anything is written, and changes made outside the app are either adopted or raised as a conflict.
SQL panel
Run read-only queries against the open file, then export the result to a new CSV or apply it back with a preview first.
Local first
No account, no cloud, no telemetry. The app only ever touches the files you point it at, on the machine you are sitting in front of.
Keyboard first
Ctrl K for any command, / to search, N for a new record, ? for the whole map.
Long text, rendered
Markdown in a cell reads as prose, so a note stays readable in the grid. The raw text sits one tab away when you need to see exactly what the file holds.

FAQ
Questions, answered.
If something about your file is unclear, these are the answers the app itself gives.
See it in the gridIs my CSV uploaded anywhere?
No. CSVita opens the file on your computer and writes back to the same file. There is no account and no server copy — the status bar says All changes saved to disk when the grid and the file agree.
Do I need to import the file first?
No. Open calls your file picker directly — the file you pick is the answer, so there is nothing left to confirm. Its columns become the sheets you see, and Create writes a new CSV with a single ID column if you would rather start from nothing.
Can I keep opening it in Excel?
Yes. CSVita reads and writes plain CSV: the same comma-separated text, UTF-8 encoding and LF line endings the status bar reports. Edit in one app, open in the other — neither keeps a private copy.
Does it work offline?
Yes. Opening, editing and saving a file makes no network request. Every type, filter, sort and search runs on the file in front of you.
What happens when I close the app?
Nothing is written until you save. Ctrl S rewrites the CSV in place, and the status bar tells you the moment the grid and the file on disk agree again.
Your CSV is already a database.
Open the file you have. Keep the file you have.
