Open a CSV and quickly find the rows you need
If a CSV opens as a wall of commas or looks misaligned in a text editor, viewing it as a table makes it much easier to check records. Use this page to find a value, sort a column, and review suspicious blanks before you import or share the data.
1. Load the original CSV
Drop your .csv file, browse for it, or load the sample. If columns appear shifted, check whether the file uses commas, semicolons, or another delimiter and whether the first row contains headers.
2. Search before scrolling
Search for a customer, product, order number, or other value to narrow down the rows that matter. Check the full row around each match rather than relying on one cell alone.
3. Sort and inspect columns
Select a column heading to sort its values. Sorting can bring unusual entries or empty cells into view, but text values that look like dates or numbers may not sort the way you expect.
4. Confirm the data before using it
Look for blank fields, unexpected headers, duplicate-looking rows, and values that may lose leading zeroes in spreadsheet software. Use the available copy or export action if you need to take the inspected data into another step.
When a viewer is not enough
This page is for inspecting a table. If you need to profile columns and check missing-value patterns, use the CSV Analyzer. If you need to change delimiters or move the data into a workbook, choose a converter instead.
Frequently asked questions
Why do all my CSV values appear in one column?
The file may use a different delimiter or quote convention than expected. Check how the source exported the file and try the appropriate import settings if available.
Will opening CSV change the original file?
Viewing and sorting are for inspection. Keep the original file and confirm any exported copy before using it as the new source of record.
Frequently Asked Questions
Is my CSV file uploaded to any server?
No, 100% private. Your CSV file is read and rendered locally inside your browser using client-side JavaScript. No data is ever transmitted over the network.
Which delimiters are supported?
The tool automatically detects comma (,), tab (\t), semicolon (;), and pipe (|) delimiters.
Can I sort and filter CSV columns?
Yes! Click any column header to sort ascending or descending, and use the search bar to filter rows dynamically.
How are quoted fields and empty cells handled?
The RFC 4180 parser accurately handles escaped quotes and highlights empty cells with distinct badges for fast data quality inspection.
