Hey Product Hunt community! 👋 I built FixMyCSV out of personal frustration. Whenever I export data from legacy platforms, I constantly deal with trailing whitespaces, duplicate entries, and messy quotes that crash imports. Uploading sensitive client datasets to random cloud tools is an immediate privacy risk. That’s why FixMyCSV is built to run 100% inside your browser via client-side JavaScript. - Zero backend servers: No data leaves your machine (feel free to inspect the Network tab). - Instant cleanup: Trim whitespaces, deduplicate records, remove empty lines, and normalize formatting. - Frictionless workflow: Instant local download. I'd love to hear your thoughts and any edge-case formatting issues you frequently encounter. Thanks for checking it out!
