CSV, TSV, and delimited text files are supported.
Applies to uploaded CSV files. If characters look wrong, choose an encoding. CSV exports use UTF-8 and keep the delimiter.
Split and merge append new columns and keep the originals. Number output uses a decimal point without grouping. Dates need an explicit order; invalid or imprecise values stay unchanged.
Use Ctrl/Command to select multiple columns.
Paste tab-separated cells from a spreadsheet starting at the focused cell. Rows follow the current sort and filters. Undo: Ctrl/Cmd+Z; redo: Ctrl/Cmd+Shift+Z.
Select a column heading to sort.
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.
Open delimited files, inspect rows and columns, search across the table, filter one column, sort values, and edit individual cells.
Use this viewer for table navigation and cell edits. Use CSV Formatter when you mainly need to normalize or reformat delimited text.
There are no fixed file-size, row, column or cell-count limits. Processing depends on available device resources. The table is paged for viewing, while downloads contain the complete data.
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.
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.
