CSV workflow
Batch converter
Paste CSV, type rows manually or upload a .csv file with default columns value,from,to. Convematik processes up to 100 rows and appends result and error columns for download.
Input rows
Extra columns are preserved. Rows with invalid numbers or incompatible units keep exporting with an error message instead of stopping the whole batch.
Results
Run the batch converter to see row results.
| value | from | to | result | error |

When to use the batch converter
Use this page when the task is no longer a single answer. Paste rows from a spreadsheet, upload a small CSV, or keep extra columns such as notes, SKU, source file or destination system. The converter appends result and error columns so a few bad rows do not block the rest of the file.
- Best fit: cleanup lists, shipping tables, product specs, classroom answer keys and small migration files.
- Expected columns:
value,fromandto; additional columns are preserved. - Quality check: test one row on a focused tool page first when the unit pair is unfamiliar.
- Automation path: use the developer API when the same batch conversion becomes recurring or server-side.
CSV accuracy and privacy notes
The browser workflow is designed for small, inspectable CSV jobs. Invalid numbers, incompatible unit pairs and unknown aliases return row-level errors instead of silently guessing. Review the exported CSV before importing it into accounting, inventory, engineering or publishing systems.
