CSV Viewer
Upload or paste CSV — sortable, searchable table in your browser
About the CSV Viewer
This CSV viewer opens a file as a sortable, searchable table in your browser. It is read-only by design, so you can inspect an export without Excel silently reformatting dates or stripping the leading zeros from codes.
A CSV viewer is what you want when the goal is to read a file, not edit it. Opening a CSV in Excel is risky: it reformats dates by locale, turns long codes into scientific notation, drops leading zeros from postcodes, and then offers to save those changes back over your file.
This viewer parses the file and shows it as a table. Sort by any column to spot outliers, search across every field to find a specific record, and see the row and column counts to confirm you received what you expected.
Because nothing is written back, the file on disk is untouched. Handy for checking a client export before importing it, or confirming a generated CSV looks right before it goes to a customer.
How to use the CSV Viewer
- Open your CSV. Upload the .csv file or paste the data directly.
- Read the table. The parsed rows appear as a table with the header row as column titles.
- Sort and search. Click a column to sort, or search to find a specific record.
- Close when done. Nothing is saved or written back, so the original file is unchanged.

Frequently asked questions
Why not just open the CSV in Excel?
Excel reformats dates, strips leading zeros and converts long codes to scientific notation, then offers to save those changes.
Can I edit the data here?
No. This viewer is read-only by design. Use the CSV editor if you need to change values.
Can I sort and search the rows?
Yes. Click any column heading to sort, and use the search box to find a record across all fields.
Is my file uploaded?
No. The file is parsed in your browser and never sent anywhere.
Does it handle quoted fields with commas?
Yes. Quoted fields, including ones containing commas or line breaks, are parsed correctly.
