How to Use the CSV Viewer Editor Online
Upload a CSV file
Select or drag and drop a CSV file into the upload area. The tool validates the file type, reads the header row, and shows row and column counts.
Search, sort, and filter data
Use global search to find text across all columns, filter by a selected column value, or sort rows by any column in ascending or descending order.
Edit CSV cells inline
Click any visible table cell and update the value directly. The edited value is kept in the browser table until you reset or download.
Hide or show columns
Use column visibility controls to hide columns that are not needed during review. Hidden columns are still kept in the downloaded CSV.
Download edited or filtered CSV
Enter an output file name, then download the full edited CSV or only the currently filtered rows.
Use global search when you want to find text across every CSV column. This is useful for searching names, emails, IDs, invoice numbers, status values, or keywords in large CSV exports.
Use column filter when you want to review only rows with a specific value in one column. For example, filter a status column by Active, a city column by Mumbai, or a department column by Finance.
Use Download Edited CSV to export the full edited dataset, or Download Filtered CSV to export only the current search and filter result.

Search, sort, filter, and edit
Find values, filter rows, sort columns, hide unnecessary columns, and edit cells inline before downloading the updated CSV file.

Download the complete edited CSV or export only filtered rows with a custom output file name for reports, uploads, and sharing.
