What to check in the finished file
The goal is a usable result, not merely a file with a new extension. For this workflow, turn a CSV file into an Excel workbook with real numbers and dates.. Before using converted data in a production workflow, verify headers, missing values, dates, numeric precision and character encoding with a small representative sample.
- Open the saved file and confirm it is complete and readable or playable.
- Compare the output with the original, especially text, dimensions, audio and page order where relevant.
- Check that the file meets the target app’s upload, compatibility or size requirements.
Common problem and how to avoid it
Automatic type detection can misread identifiers and ambiguous dates. If the first result does not meet the requirement, return to the original and adjust the relevant settings rather than repeatedly converting an already degraded output.
