DOC is a document format: it stores formatted text in a binary compound-document structure, requiring Microsoft Word or a compatible reader to render correctly. CSV is a spreadsheet format that stores tabular data as plain text with one row per line and field values delimited by commas, readable by any spreadsheet or database tool. This extracts structured tabular data from the document into an editable spreadsheet format. Metadata such as creation date and embedded colour profiles is preserved where the target format supports it. Converting between these two formats is common when the source application does not support CSV natively or when the target platform only accepts CSV. 1converter processes this conversion server-side using open-source tools. Files are transferred over HTTPS, converted on secure cloud servers, and automatically deleted after 24 hours.
