Why does the Bulk Checker Pro return invalid ASIN when I upload a file with ASIN's that are all numbers ?
When using copying a list of ASINS that are numbers that begin with zeros most spreadsheets apps remove these leading zeros. To prevent this, you can first apply the Text format to the cells before you type or paste the numbers.
For Microsoft excel:
- Select the cells on your worksheet where you’ll be adding the data.
- On the Home tab, click Number Format >Text.
For Google Sheets
1.Select the cells on your worksheet where you’ll be adding the data
2.On the Format tab, click Number >Plain Text
