Answer 1

Are you attempting to import into a newly made table or into an existing table? It looks like it's trying to insert data where it cannot be inserted (invalid column or lack of data size in your column).
Try the following:
1). In your excel sheet, highlight the whole sheet and make sure the cells are in 'text' form and try re-importing
2). save the document as ms dos TEXT and import as a text document.
3). double check your columns are correct for the data, for example if you have a column that has a string of 100 characters and your column is 'NvarChar(90)' - that might cause the error? Or just correct data type in your column
3). If that doesn't work and you're inserting into a new table, try importing it as string first and writing a query to insert columns that should be float/integer or whatever. You may want to convert float texts to a 'bigint' first rather than string
> float as that can cause problems if I remember correctly.
