Does Deliteful preserve Excel formulas in the output?

No. The output contains row data values only — formulas, styles, and formatting are stripped. For data pipeline use this is typically preferable since you want raw values, not formula references.

Can I filter multi-sheet workbooks?

Yes. Every worksheet containing the specified column is filtered. Sheets that do not contain the column are skipped and excluded from the output file.

What happens with non-numeric values in a numeric greater-than or less-than filter?

Rows where the target column contains a non-numeric value are silently skipped for numeric comparisons. They do not appear in the output, which avoids type errors in downstream processing.

Does column name matching respect case?

Yes. The column name you enter must match the header in your Excel file exactly, including capitalization. If your export uses 'amount' but you enter 'Amount', the column will not be found and the file will be excluded from the output.

Row-Level Excel Filtering Without the Pandas Boilerplate

Data engineers occasionally receive Excel files from business stakeholders that need a quick row filter before being handed off or ingested into a pipeline. Writing a pandas script for a one-off filter is overhead that doesn't scale as a pattern. Deliteful handles the filter server-side and returns a clean .xlsx output in seconds.

The typical scenario: a business analyst sends a 50,000-row Excel export and asks you to pull only rows where Status equals 'Pending' or where Amount exceeds a threshold before you load it into the warehouse. Deliteful handles this without you opening Excel or spinning up a notebook. Upload, set the column and condition, download the filtered file.

Deliteful supports equals, contains, greater than, and less than conditions. Only one condition runs per job, which is intentional — it keeps the tool deterministic and auditable. For multi-condition filtering, you can chain runs or handle complex logic in your pipeline tooling. The output is a standard .xlsx file, and multi-sheet workbooks are filtered per worksheet.

How it works

1
Upload the Excel file
Upload the .xlsx or .xls file you received or need to pre-process.
2
Name the target column
Enter the exact column header — case-sensitive — that you want to filter on.
3
Set the condition and value
Pick one: equals, contains, greater than, or less than, and enter the filter value.
4
Download and use the output
The filtered .xlsx is ready to ingest, forward, or diff against the original.
