About CSV
CSV (comma-separated values) is the universal format for spreadsheets and data exports. The first row holds column names and each following row is one record.
About HTML Table
An HTML table is ready to paste into a web page, CMS, email template or documentation site.
How it works
Nested objects are flattened into dot-separated column names (for example address.city) and arrays are written as JSON inside a cell. If your CSV wraps a list in an object, the list is used as the rows.
Private by design
Developer data is often sensitive: API responses, tokens, customer records, internal configs. This CSV to HTML Table processes everything locally in your browser tab. There is no server round-trip, no logging and no storage of your input.
