CSV Viewer & Editor Online

Drop a CSV file here or click to choose

CSV, TSV, and delimited text files are supported.

Browse CSV, TSV, and other delimited text as a table, then search, sort, filter, and edit the data without leaving the page.

Edit cells directly, rename columns, add rows or columns, and export the complete edited table. Search, filters, sorting, and pagination only change the view; they do not remove rows from the exported file.

Browse and edit CSV as a table

Open delimited files, inspect rows and columns, search across the table, filter one column, sort values, and edit individual cells.

CSV Viewer vs. CSV Formatter

Use this viewer for table navigation and cell edits. Use CSV Formatter when you mainly need to normalize or reformat delimited text.

CSV viewer and editor FAQ

How large can a CSV file be?

This page accepts files up to 50 MB and limits a table to 200,000 rows, 250 columns, or 2,000,000 cells. Very large tables still depend on the memory and speed available on your device.

Does the viewer support commas and new lines inside a cell?

Yes. Quoted fields may contain delimiters, escaped quotation marks, and line breaks. Choose the correct delimiter manually if automatic detection does not match the file.

Will exports include all of my edits?

Yes. CSV, JSON, and XLSX exports use the entire edited table, including changes that are currently hidden by a search, filter, sort order, or another page of results.

Is my CSV data uploaded?

No. The selected or pasted data is parsed and edited in this browser tab by this tool. It is not uploaded to a server.
