Sheet facts
Excel's own Save As writes a CSV from the active sheet only. A workbook with twelve monthly tabs means twelve saves, and the older CSV option turns accented or Asian text into question marks. XLS to CSV Converter reads every sheet of every workbook in a folder and writes clean CSV UTF-8 files in one run.

Why Excel's own CSV export falls short
Save As CSV in Excel writes one sheet and drops the rest without warning. Select the wrong CSV type and non-English text breaks. This converter exports all sheets at once and uses UTF-8 by default, so names in any language survive.
Core features
Load the workbooks, check the sheets, narrow the rows, choose a save mode and convert.
Load
Click Open and select Choose Files for single workbooks or Choose Folders for a directory full of them. XLS, XLSX, XLSM and XLT files load side by side.
File list
Every loaded workbook appears in the converter's file list. Tick the ones to convert and leave drafts or old copies out.
Sheet preview
The converter shows the sheet in rows and columns before anything is written, so a wrong header or an empty tab shows up early.
Selective export
The search bar above the preview narrows a sheet by keyword. Export one region, one customer or one month of rows and skip the rest.
Save options
Three save modes cover most jobs. Save all sheets as separate files, save sheets into a single file or merge them into one CSV under a common header. No Sheet Header drops the header row when the target system does not want it.
Before converting
CSV keeps values only. A few checks in Excel first save a second run.
Formulas
Results reach the CSV, not formulas
A CSV stores the value a cell shows. If a formula still reads #REF! or #N/A in Excel, fix it there first or that error text lands in the CSV.
Leading zeros
Store codes as text
ZIP codes and phone numbers lose leading zeros when a CSV is double clicked open in Excel. Format those columns as Text in the workbook and import the CSV through Data, From Text later.
Delimiters
Check what the target expects
Most systems read a comma. Some European setups expect a semicolon because the comma is their decimal mark. Confirm the import settings of the receiving app first.

Excel can save a CSV without extra software. For one sheet that is enough. Folders of multi-tab workbooks are where a dedicated converter earns its price, as the rows below show.
| Job | Excel Save As | XLS to CSV Converter |
|---|---|---|
| Cost | Included with Excel | $29 one time |
| One sheet, once | Works fine | Works too |
| Multi-tab workbooks | Active sheet only | All sheets in one pass |
| Folder of workbooks | One file at a time | Full folders in a batch |
| Non-English text | UTF-8 chosen by hand | UTF-8 by default |
| Merged output | Copy and paste | One CSV, common headers |
| Header row control | Edit the sheet first | No Sheet Header option |
| Excel installed | Required | Not needed |
Green rows mark where Excel's own Save As is enough.
For one sheet, Save As with the CSV UTF-8 type does the job. CSV work for mailbox data is described in Export Outlook emails to CSV .
