View, sort, filter, and edit CSV files in a spreadsheet-like interface with search and column operations.
A CSV file becomes an editable grid with records arranged as rows and fields arranged as columns. The viewer supports searching, sorting, filtering, direct cell edits, and column operations, making it useful for inspecting structured text without reading raw delimiters. Processing stays in the browser. The most common parsing surprise is that a comma inside a value is still a separator unless the complete field is enclosed in double quotes.
A concrete input and expected output from the current implementation.
Input
product,notes Mug,"red, large" Pen,blue
Expected output
product | notes Mug | red, large Pen | blue
The first record supplies two column names, and the next two records supply their values. Quoting keeps the comma in "red, large" inside one notes cell; the surrounding quotes are CSV syntax rather than cell content.
Each CSV record becomes a grid row, and its comma-separated fields become cells. A header record, when present, labels the columns. Double-quoted fields can contain commas without creating extra cells. Within a quoted field, a literal double quote is represented by two consecutive double quotes.
Once the table is visible, search locates matching content, filters restrict which records are shown, and sorting arranges rows by a selected column. Values can be changed directly in the spreadsheet-like view, while the available column operations act on fields rather than requiring manual edits to every raw CSV line.
No. The file is handled in the browser, so viewing, searching, sorting, filtering, and editing do not require uploading its contents. Still keep an untouched copy of important source data until you have checked the revised table, especially when delimiters, quoting, line breaks, or character encoding may affect interpretation.
No. An XLSX workbook can contain multiple sheets, formulas, formatting, charts, and typed cells that CSV cannot represent. Export the relevant worksheet as CSV first, then open that file in this tool. Expect the resulting flat rows and columns, not the workbook's formulas, formatting, sheet structure, or visual layout.
