Xlsm is a file format in Excel that supports macro code. It can use advanced features in Excel to process large data or perform complex analysis, while also being manageable in team collaboration due to its small size and strong compatibility. When you need to use macros in Excel, process complex data in files, and automate these tasks, convert Excel spreadsheets to Xlsm. Below is an introduction on how to quickly convert a large number of Excel spreadsheets to Xlsm format.

When macro code is included in an Excel worksheet, the Xlsm format can save and run these macros. It plays a critical role in scenarios requiring automated processing and custom functions. Moreover, the Xlsm format supports advanced Excel features (such as Power Query, Power Pivot), making it suitable for batch processing of large data or complex analysis. The following explains how to batch convert various file formats in Excel tables to Xlsm format, addressing scenarios where macros are needed, complex data is processed, or automated functions are shared. It supports formats such as Xls, Xlsx, Xlt, and Xlts.

When an Excel worksheet needs to handle very large datasets, converting to the Xlsb format not only results in a smaller file size but also offers faster read/write speeds, allowing you to store and manipulate millions of rows of data. When running complex macro code, the Xlsb format provides more efficient support for VBA macros. Also, when frequently working with data, it delivers better performance for opening and saving files. Converting Excel spreadsheet files to the Xlsb format is suitable for scenarios involving processing big data, running complex macros, improving performance, or enhancing data security.

When sharing files with users of older versions of Excel 2003 or earlier, the file may have a version that is too high. The Xls format can ensure compatibility and prevent issues such as file inaccessibility or formatting errors caused by version differences. Additionally, in some enterprises and organizations, internal system software may only support the Xls format. Converting to the older Xls format can ensure smooth data import and processing.

When creating custom functions or tool libraries, the Xlam format can be used as an add-in for Excel worksheets, making it easy to reuse across multiple workbooks for developing complex calculation tools and data analysis features. Additionally, the Xlam format also supports VBA macro code and is suitable for automating tasks and enhancing Excel functionality. If files like Xls or Xlsx need to extend their functionality or use VBA macro code, converting them to Xlam can improve work efficiency and data analysis consistency.

The TXT file format, as a plain text format, boasts strong compatibility and can be directly read and processed by most programming languages, databases, and analytical tools. During data migration or backup, the TXT format features a simple structure and small file size, allowing it to store and transfer large amounts of data. Even in scenarios requiring data cleaning, analysis, or cross-platform data sharing, the TXT format's plain text nature facilitates script operations while also enabling transfer between different operating systems without the need for specific software.

As a vector graphics format, SVG can be infinitely scaled while maintaining high definition. In the Sheet of an XLSX worksheet file, there are charts, data, and other elements to be displayed, which can be directly converted to SVG format, allowing the content in the spreadsheet to be previewed with high clarity. Moreover, the SVG format also supports embedding into web pages for development and is supported by all modern browsers and design software, ensuring charts display consistently across different devices and systems. Compared to Excel spreadsheets, converting to SVG format offers higher compatibility and flexibility, meeting more scenario requirements.

When embedding Excel charts into web pages, PPTs, or printed materials, such as creating interactive web reports, academic paper illustrations, or promotional posters that require high-definition display and data visualization, you can use the SVG format. As a vector graphic, SVG can be scaled up infinitely without losing quality. Compared to bitmap formats like JPG or PNG, SVG files are smaller in size, store only dynamically modifiable styles, and can even control animation effects directly through code. Here's how to batch convert a large number, even up to thousands, of Excel spreadsheet files into the SVG vector graphics format, supporting various worksheet formats such as Xls, Xlsx, Xlt, Xltx, and Xlsb.

When sharing or submitting XLSX spreadsheet data, PDF ensures a fixed file format, preventing layout or data corruption caused by different devices or software versions. Especially in formal reports and financial documents, PDF is more professional and secure compared to Excel spreadsheets. If the XLSX spreadsheet contains sensitive data, converting it to PDF allows you to set encryption or permission settings to protect the content, providing a secure transmission environment.

In daily office work, a common scenario when dealing with Excel worksheets is the need to distribute tables to others. However, after sending Xls or Xlsx files to the recipient's computer, the formatting and layout often become completely disorganized, and the fonts may change. Converting them to PDF locks the chart and data content within the tables, ensuring they appear exactly the same as the original file on any computer or mobile phone, without display issues. If the recipient's computer does not have Office software installed, or if they can only receive files on a mobile device, converting to PDF significantly improves the viewing experience, and the files can be opened on almost any device. For important data tables such as company financial reports, customer information, and contract quotations, previewing them in Xls or Xlsx format makes it very easy to accidentally modify them. Converting to PDF is like locking the file, preventing data from being tampered with. When printing tabular content like monthly reports or annual summaries, PDF format also ensures print quality and long-term preservation after printing. Sometimes Excel files contain a large amount of data and are therefore very large in size. After converting to PDF, the file becomes much smaller, making it more convenient for transfer or uploading to websites. Especially in scenarios where only data display is needed without editing, PDF files better showcase their advantages. Ensuring consistent table content display across all devices, protecting important data, or making the table look more professional—converting to a PDF document can avoid a lot of trouble and significantly improve work efficiency. So, how can we batch convert 10, 100, or even 1,000 Excel spreadsheets into PDF documents?

Numbers is a native application within Apple's ecosystem. When you need to view or edit Excel spreadsheets on a Mac, iPhone, or iPad, converting them to the Numbers format offers better compatibility, supports iCloud syncing, and facilitates cross-device collaboration. Additionally, the Numbers interface is streamlined and intuitive, with a variety of built-in beautiful templates and chart styles, allowing users unfamiliar with Excel's complex features to get started quickly.

Json is a lightweight data exchange format that can be directly parsed and used by most programming languages and platforms when interacting with web applications. In the development of separated front-end and back-end, Json is also the standard format for data transmission between the front-end and back-end, used to store and transmit structured data. When multiple Xls, Xlsx, and other format files need to be converted for web development, data interaction, or cross-platform data processing, batch conversion to Json format can improve efficiency in various aspects.

After receiving or creating an Excel spreadsheet at work, you often need to save it as an image for use, but images obtained directly with screenshot tools are often not clear enough. In this case, we can adjust the PPI parameter before saving to get a very high-definition image. For example, by setting the PPI of a printed report to 300 PPI, the printed data and charts are clearer than normal export. When transferring and previewing across different devices, inputting 200 PPI not only keeps the file size from being too large, but also ensures clear viewing on both phones and computers. In short, PPI is a very important indicator for measuring image clarity; the higher the PPI value, the higher the image resolution will become along with PPI, and the clearer the image will be. So how can we set the PPI in advance to ensure image quality before batch exporting many Xls and Xlsx format files as JPG images? Here is a practical tip to quickly export spreadsheets as high-definition JPG, greatly improving our work efficiency!

In scenarios involving data presentation, protection, or design, Xlsx worksheets cannot be fully comprehensive. Converting them to JPG image format can solve many problems. For example, displaying key data in meetings or presentations, embedding tables into documents, archiving and backing up important information, ensuring cross-platform compatibility, and quickly previewing the first, second, or the first few key contents. Batch converting certain sheets from multiple Xlsx tables into JPG images can improve work efficiency, protect data integrity, and enhance file universality and preview.

JPG is the most common image format. It has strong versatility and is suitable for sharing on web pages and social media, facilitating online distribution and display. It can also be directly inserted into Word, PPT, or other documents. In scenarios where there are many Excel worksheets but you do not want to open the files yet need a quick preview, batch conversion to JPG image format can enhance file security and usability.

After creating charts in Excel, you may need to send them to others for review without allowing them to modify the prepared data. Converting them into non-editable JPG images can solve this issue. Important reports, annual summaries, and similar documents often require long-term preservation. An Excel spreadsheet might look different when reopened after several years, resulting in formatting errors or compatibility issues that prevent it from opening. However, once converted to an image, it is permanently frozen at that moment and can be opened on any device. Sometimes, to let people quickly grasp the data without diving into excessive analysis, converting to JPG is also useful. For example, data briefings made with Xlsx worksheets for meetings, or key content for press releases—images provide a clear preview without overwhelming information. When creating corporate brochures or product manuals, converting tables to images also helps maintain a consistent style across all pages. In summary, after completing Xls, Xlsx, or other spreadsheet files, if you need to protect data security, preserve it for the long term, and ensure that everyone can view it properly, converting all Sheet pages in an Excel file into non-editable JPG images is an indispensable solution. So how can we batch convert all Sheets in Excel into JPG images?

A complete JPG long image can avoid the problem of viewing by page, ensuring all content is fully presented in one image, making it easy to preview and save. When content from multiple Excel tables is needed to create reports, documents, or presentation materials, batch converting all sheets in a worksheet to a single JPG long image can simplify layout and avoid formatting errors. In scenarios involving printing or saving, a long image also ensures the data layout remains complete and consistent, eliminating concerns about misalignment caused by pagination.
