How to use Fix a Broken CSV
- 1. Paste your broken CSV. Drop the malformed comma-separated data into the input pane, including unclosed quotes, missing fields or rows with an inconsistent number of columns.
- 2. Let the tool repair the structure. The repair closes unterminated quotes and pads short rows with empty fields so every row matches the widest row's column count. There are no settings to configure.
- 3. Copy the fixed CSV. Copy the repaired output and check it against the original to confirm the fix matched your intent, since automatic repair guesses at the most likely correction for each issue.
When to use Fix a Broken CSV
Fix a Broken CSV automatically repairs common structural problems in a CSV file, like an unclosed quote or a row missing trailing fields, that would otherwise break a strict parser. It's a first pass for salvaging a damaged export before deeper cleanup.
- Recovering a truncated export. A download was cut off partway through and left a quote unclosed at the end of the file. Running the repair closes the quote so the rest of the file still parses.
- Handling inconsistent row lengths. Some rows in an export are missing trailing commas because a source field was empty. Padding short rows to match the widest row prevents a parser from misaligning later columns.
- Salvaging a manually edited CSV file. Someone hand-edited a CSV in a plain text editor and accidentally broke the quoting around a field with a comma inside it. The repair step catches and closes that kind of mistake.

About the Fix a Broken CSV tool
Fix a Broken CSV runs as plain JavaScript in your browser tab, with no server behind it. Automatically fix a broken CSV. 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.
There is nothing to configure. Provide the input and the result appears on its own. 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 Fix a Broken CSV 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.
