The editor of Downcodes brings you a detailed explanation of common suffixes in Excel tables. Excel file formats are diverse, and .xlsx, .xls, .xlsm, .csv and other suffix names represent different file types and characteristics. This article will delve into the differences and usage of these common suffixes to help you better understand and use Excel tables. I hope this article can help you better understand and use Excel and improve your office efficiency.
The suffix of Excel tables is usually .xlsx, .xls, .xlsm, .csv. The most common is .xlsx, which is the default file format used starting with Microsoft Office 2007, which is based on the XML format and supports larger data capacity and more worksheets. Compared to its predecessor .xls, .xlsx provides better data compression and improved file recovery capabilities. Early versions of Excel used .xls as the file suffix, but because it was more restrictive for modern applications, it was gradually replaced by .xlsx. For macro-enabled workbooks, the .xlsm format is typically used. In addition, the .csv (Comma-Separated Values) format is also commonly used in Excel, especially when storing and transferring tabular data. Due to its text format storage, it has high compatibility.
.xlsx is the default file extension for the Excel spreadsheet program and is particularly useful for handling complex spreadsheet tasks. It is based on the Office Open XML (OOXML) file format standard, which is designed for storing and recovering document data. .xlsx files have good compression characteristics and the files are generally much smaller than equivalent .xls files. Because it is based on XML, it not only facilitates data exchange between Office applications, but also facilitates programmatic processing.
Extended features:
Supports backward compatibility: Through Microsoft Office's compatibility pack, older Excel programs can also open .xlsx files, although some new features may not be available. Data recovery capability: The .xlsx format improves the recovery capability of damaged files, which is crucial for users to avoid data loss. Support more rows and columns: In .xlsx format, a single worksheet can support up to 1,048,576 rows and 16,384 columns, which far exceeds the limit of .xls format..xls is the file format used in earlier versions of Excel. It is based on binary composition, which means that it directly contains the byte data of the spreadsheet. Although it is compatible with many devices, it has been gradually replaced by new versions because it supports a smaller number of rows and columns, and its functions are not as rich as .xlsm and .xlsx.
Compatibility issues:
Compatibility: Although new versions of Excel still support opening .xls files, older versions of Excel may not be able to open .xlsx files that use new features. Capacity limitation: The .xls format can only support up to 65536 rows and 256 columns, which is obviously not enough for users who need to process large amounts of data.The .xlsm format is a macro-enabled Excel workbook file format. Macros are a series of commands and instructions used to automate repetitive tasks in Excel. Due to the possibility of containing code execution, .xlsm files require greater caution regarding network security than other Excel file formats.
Suggestions for use:
Security: .xlsm files containing macros should only be opened if the source is trusted. Compatibility: All modern versions of Excel can open .xlsm files, but running macros may require the user's explicit permission..csv is a simple file format used to store tabular data, including numbers and text. The data is separated by commas (although other characters are sometimes used as delimiters), hence the name. The advantage of .csv files is that they can be easily read and written by most spreadsheet software, databases, and programming languages.
Exchange and processing:
Data exchange: .csv files are commonly used for data export and import functions because almost all spreadsheet and database management systems support this format. Simple processing: Since .csv is a plain text format, users do not need to consider complex formatting issues in data processing like they do with Excel's proprietary formats.1. Why is the suffix of Excel table .xlsx or .xls? The suffix for Excel tables is .xlsx or .xls because they are the file format extensions used by Microsoft Excel software. .xlsx is the default file format used by Excel 2007 and later versions, while .xls is the file format used by Excel 2003 and earlier versions. Such suffixes enable computers to recognize the file type and associate it with appropriate software.
2. In addition to .xlsx and .xls, are there any other suffixes for Excel tables? Yes, Excel tables can be saved in other formats besides .xlsx and .xls. For example, .csv (comma-separated values) files are a common and widely used spreadsheet file format that store data in plain text with commas separating each field. There are other less commonly used suffixes such as .xlsm (Excel table containing macros) and .xml (Excel table stored in XML format).
3. How to change the file extension of Excel table? To change the file extension of an Excel table, you need to perform the following steps:
First, open the Excel table file containing the suffix you want to change. In the Excel software, click on the "File" tab and select the "Save As" option. In the pop-up Save As dialog box, select a new folder or location to save the file. In the Filename field, enter the new filename you want to change, including the desired new suffix. Click the "Save" button to complete the file extension change operation.Please note that you need to be careful when changing file extensions to ensure that you select the appropriate file format to avoid data loss or inability to open the file correctly.
