How to use Convert CSV to 0SV
- 1. Paste your CSV. Drop the comma-separated rows into the input pane. Every comma between fields is replaced with a NUL byte, the delimiter that gives 0SV, null-separated values, its name.
- 2. Choose how the NUL byte displays. Turn on Show NUL as the visible symbol so the delimiter appears as a readable placeholder character in the output pane, since a real NUL byte is normally invisible on screen.
- 3. Copy the 0SV output. Copy the result and use it wherever a NUL-separated format is expected, such as piping into command-line tools that treat NUL as a safe delimiter for filenames or paths.
When to use Convert CSV to 0SV
Convert CSV to 0SV replaces commas with the NUL byte, producing null-separated values that some command-line tools rely on because NUL can never appear inside a legitimate filename or path. Reach for it when you're feeding data into a shell pipeline that expects that convention.
- Piping filenames safely through a shell command. Tools like find and xargs support NUL-separated output specifically to handle filenames with spaces or newlines safely. Converting a CSV of paths to 0SV matches that convention.
- Avoiding delimiter collisions in messy data. A CSV export contains values with embedded commas that make normal parsing risky. Since NUL is guaranteed not to appear in text data, switching delimiters removes that ambiguity entirely.
- Feeding a script that expects null-separated input. A build or automation script explicitly reads NUL-delimited fields for robustness. Converting your CSV export to 0SV first makes it compatible without rewriting the script's parser.

About the Convert CSV to 0SV tool
Convert CSV to 0SV runs as plain JavaScript in your browser tab, with no server behind it. Convert a CSV file to a null-separated values file (0SV). Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's CSV Tools section, 133 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with the Show NUL as ␀ (visible symbol) setting, and the result refreshes the moment you change it. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Is Convert CSV to 0SV free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
