FAQ
Does Advanced ETL Processor automate working with Excel files?
Yes. Advanced ETL Processor reads, creates, updates, splits, merges, validates, and schedules Excel workflows without Excel macros or hand-built scripts.
Do I need Microsoft Excel installed on the server?
No. Routine Excel automation runs as a self-hosted ETL workflow without opening Excel on the desktop.
Is Excel data validated before loading?
Yes. The workflow checks required fields, data types, duplicates, lookup values, date formats, and rejected rows before writing to a database or report.
Are failed Excel files separated from good files?
Yes. A workflow moves failed workbooks to an error folder, keeps the original file, writes logs, sends notifications, and continues with valid files.
Do Excel templates preserve formatting and formulas?
Yes. Template-based workflows keep layout, formulas, sheet structure, and formatting while filling the workbook with current data.
How should missing sheets or columns be handled?
Define the rule before scheduling: stop the job, skip the file, create a clear error record, or route the workbook to a review folder.
Is there a trial for Excel automation?
Yes. Download the fully functional 30-day trial and build a small Excel workflow first.
When should I not automate an Excel process yet?
Do not automate it until the workbook layout, sheet names, column rules, output folder, and failure handling are clear. Automation repeats rules; it does not read minds.
Stop fixing broken spreadsheets by hand. Start loading clean data automatically.
If your Excel imports fail every month, automate the workflow directly and keep raw files untouched.
