What the tool does
The table converter quickly transforms CSV, TSV, Markdown table, HTML table, and JSON. It is useful for exports, product lists, documentation, content, admin panels, and data preparation without uploading anything to a server.
How to use it
- Paste a table or JSON into the source field.
- Choose input and output format, headers, and delimiter.
- Copy the result or download the file.
Formats and conversion directions
The converter works with CSV, TSV, Markdown table, HTML table, and JSON. Choose the source and target format to turn a documentation table into CSV, API JSON into Markdown, or an HTML table into import-ready data.
JSON can be a single object, an array of objects, or an array of arrays. When exporting to JSON, the header option controls whether rows become objects with keys from the first row or remain arrays.
Table settings
For CSV, you can use comma, semicolon, pipe, or a custom delimiter. TSV uses tabs. Cell trimming removes extra whitespace around values, and pretty JSON makes the output easier to read.
The tool shows row and column counts, which helps spot parsing problems quickly: for example, a wrong delimiter or an unclosed quote in the source table.
Limits and privacy
The converter is best for regular rectangular tables. Complex HTML tables with merged cells, nested JSON objects, and non-standard Markdown may need manual cleanup before conversion.
Data is processed locally in the browser and is not sent to the All Tools server. For very large tables, speed and success depend on device memory and browser performance.
