Why CSV is everywhere, and its quirks
CSV endures because it is simple and universal: almost every spreadsheet, database and data tool can read and write it, making it the common language for moving tabular data between systems. But its simplicity hides real quirks that cause trouble — how to handle commas inside a field, quotes, line breaks within cells, and different delimiters all vary, which is why a CSV that opens fine in one program can look mangled in another. Working with CSV in a dedicated tool that understands these quirks avoids the corruption that comes from treating it as plain text. The privacy angle matters too: data in CSVs is often sensitive — customer lists, financial records, exports from private systems — so processing it locally in your browser, rather than uploading to an online converter, keeps it under your control, which is exactly what you want for data you would not want on someone else's server.
