Convert a small table, check quoted commas and leading zeros, and compare the exported values with the original data before replacing a file.
A conversion is only useful if the values still mean the same thing afterward. Codes such as 0012 should not silently become the number 12, and a comma inside a quoted address should not create an extra column.
Worked example: Keep an identifier and a quoted comma
Input
code,city 0012,"Paris, France"
Expected result
One record with code "0012" and city "Paris, France". The comma belongs inside the city value.
Check the converter's number-detection setting before exporting. Leading zeros are often meaningful in identifiers even when the characters look like a number.
Before you use the result
- Check the delimiter and whether the first row contains field names.
- Inspect empty values, leading zeros and quoted commas.
- Compare the record count after conversion.
If the result is not what you expected
Every value appears in one column.
The file may use semicolons or tabs instead of commas. Choose the delimiter that appears between fields in the source.
