Do Amazon Seller Central CSV files convert cleanly, including tab-delimited reports?

Standard comma-delimited CSVs convert reliably. Tab-delimited files (.txt or .tsv) that Amazon sometimes produces may need to be saved as .csv first, as Deliteful's CSV to Excel tool expects CSV-formatted input.

Will my ASIN numbers or order IDs be truncated or converted to scientific notation?

Cell values are written as text strings from the CSV source. However, Excel may auto-format long numeric strings like order IDs into scientific notation on open — this is Excel behavior, not a conversion artifact. Formatting columns as text in Excel after opening will resolve it.

Can I convert multiple Amazon reports in one upload?

Yes. Upload several report CSVs at once and each produces its own .xlsx output file.

Is there a limit to how many rows a converted file can contain?

Excel's maximum is 1,048,576 rows per worksheet. Amazon reports rarely approach this limit, but very large fulfillment reports with long date ranges could theoretically be truncated.

Convert Amazon Seller Central CSV Reports to Excel

Amazon Seller Central delivers every report — sales summaries, FBA inventory, settlement statements, search term reports — as a CSV or tab-delimited file. Getting that data into Excel for analysis, margin calculations, or PPC review shouldn't require an import wizard. Deliteful converts it directly to .xlsx.

Amazon sellers working across multiple ASINs or ad campaigns pull reports frequently. A settlement statement, a fulfillment report, and a business report might all need to land in Excel in the same sitting. Opening each through Excel's text import wizard — specifying delimiters, column types, encoding — is repetitive friction that adds up across reporting weeks.

Deliteful produces a clean .xlsx file from each CSV upload with no formatting added and no data modified. Rows are written in order, columns are preserved as-is, and the file opens directly in Excel. For sellers who then build their own margin sheets or PPC dashboards on top of Amazon's raw exports, this is the cleanest starting point.
