HTML に CSVコンバーター — 高速＆無料

The HTML file format stores data in the HTML format. Converting to CSV produces a spreadsheet file 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. This makes CSV the practical choice when the destination system requires it or when the original format is not supported by the target application. 1converter runs this conversion on the server: your file is uploaded encrypted over HTTPS, converted using trusted open-source libraries, and the output is held for 24 hours before automatic deletion.
