Turn workbook data into a CSV file
An Excel workbook can hold several tabs, but a CSV file holds one flat table. This converter opens a workbook, lets you choose which worksheet to export, and creates comma-separated text you can use in a spreadsheet, database import, or another app. You can check the rows before copying the result or downloading it as a .csv file.
Export the worksheet you actually need
When a workbook opens, the first worksheet is selected automatically. If the data you need is on another tab, choose its name from the Worksheet menu. The table updates to that sheet, and both Copy CSV and Download CSV use the selected worksheet. Export additional tabs one at a time; a CSV cannot contain multiple worksheets.
The table displays the first non-empty row as its column headings, and that row remains in the CSV as the first line. Completely blank rows are skipped when the worksheet is read. Empty cells inside a row with data remain empty, so later values stay under the correct columns.
Choose a delimiter that suits the next app
Comma is the standard starting choice. Some regional spreadsheet settings and import tools expect semicolons instead; others accept tabs or pipes. Choose the delimiter the destination expects. The selected setting is used for both the copied text and the downloaded file.
A value can itself contain commas, quotes, or line breaks. To keep that value in one CSV cell, the converter surrounds it with double quotes and doubles any quote marks inside it. You can therefore export names, notes, and addresses that contain punctuation without splitting them into unintended columns.
What spreadsheet details carry over?
CSV is plain text, so it does not keep worksheet colors, font styles, widths, charts, images, macros, or formulas as working spreadsheet formulas. The converter exports the values available in the selected sheet. A formula cell may export its saved result rather than its formula; if the workbook has no saved result for that cell, check the output before using it.
CSV also has no separate number or date types. The way a date, long identifier, or formatted number appears in the export can depend on how the workbook stores and displays that cell. Review the full table, especially for dates, codes with leading zeros, and formula results. If a specific value must keep an exact text representation, format or convert that cell to text in the workbook before exporting.
From Excel file to downloadable CSV
- Choose or drop an XLSX, XLS, XLSM, XLSB, or ODS workbook into the upload area.
- Select the worksheet and output delimiter.
- Review the scrollable table, then copy the CSV text or download the file.
Workbooks up to 50 MB are supported. The workbook is read and converted in your browser; it is not uploaded to RomitCSV. The spreadsheet-reading library loads from jsDelivr, so an internet connection is needed to use the converter.
Frequently asked questions
Can I convert an Excel workbook with several tabs?
Yes. Select a worksheet and export it as a CSV, then select another worksheet to create a separate file. CSV does not support multiple tabs in one file.
Does the first row stay in the downloaded CSV?
Yes. It is used as the table's visible column heading and is included as the first CSV row.
Can I save the result with tabs or semicolons instead of commas?
Yes. Select tab, semicolon, or pipe from the CSV delimiter menu. Comma is selected by default.
Are Excel formulas converted?
Formulas are not carried over as formulas. The export uses the value available for each cell in the workbook; a formula without a saved result may appear blank.
Why does my CSV not look like the worksheet?
CSV keeps table values, not spreadsheet formatting. Colors, font styles, charts, column widths, and other workbook presentation features are left behind.
Why are empty lines missing?
Completely blank worksheet rows are skipped. Empty cells within rows that contain data are preserved.
Is my workbook sent to a server?
No. The converter reads and converts the workbook in your browser. It does load the spreadsheet library from jsDelivr.
Choose the next format
To build an Excel workbook from delimited text, use CSV to Excel. If another tool needs structured records instead, convert the table with CSV to JSON.
