JSON (JavaScript Object Notation) uses human-readable structured data encoding and is best for APIs, configuration files, and data exchange between web services. CSV (Comma-Separated Values) uses tabular plain text encoding and excels at spreadsheets, database exports, and data imports. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
