E-commerce systems and payment gateways often export daily transaction ledgers as separate CSV files. You can combine dozens of daily transaction reports into a single consolidated XLSX spreadsheet in seconds.
Upload Daily CSV Files
Select and drop all daily CSV exports into the merge tool interface.
Configure Append Settings
Choose 'Append into one sheet' and optionally check the source-file column toggle.
Download Consolidated XLSX
Order the files chronologically and click merge to download your complete Excel ledger.
Select the single-sheet mode to keep the header row from the first file and append all subsequent transaction records sequentially underneath without repeating headers.
Enable the source filename column option to automatically tag each row with the original CSV file date or batch name, simplifying reconciliation and auditing.
No, data rows are merged based on column position (Column A to Column A), so ensure all CSV files share the same column layout.
No, the entire CSV parsing and XLSX generation process runs locally within your client browser.
