The growing complexity of business environments and the rapid digitalisation of processes demand efficient document management. Beyond security and storage, one critical aspect that many organisations overlook is the adoption of standardised formats in their document management platforms. These formats play a crucial role in ensuring the accessibility, interoperability and longevity of documents. With standardisation, companies can therefore avoid file compatibility problems, simplify data transfer between systems and ensure the long-term preservation of important documents.
As document management platforms evolve to offer more robust solutions, the need to adopt standardised file formats becomes fundamental. Sensitive documents and long-term archives need a format that guarantees future access, even as technology evolves. With this in mind, this article looks at the importance of adopting standardised formats, the main recommended formats and the challenges of implementing them in document management platforms.
Why adopt standardised formats
Standardising file formats offers a number of significant advantages, from both a technical and an organisational point of view. Below, we set out the main reasons why adopting standardised formats is crucial for efficient document management.
Interoperability between systems
In a business environment, teams often share documents between different departments, systems and sometimes even external partners. When everyone uses standardised formats such as PDF, DOCX or CSV, the exchange of information becomes more efficient and secure. Interoperability between platforms ensures that any software compatible with these standards can open and handle the documents. As a result, compatibility problems disappear and less time is spent on manual conversions.
Document preservation and longevity
Document durability is a growing concern, especially in regulated environments that require records to be stored for long periods. Choosing standardised formats such as PDF/A, designed for long-term document preservation, ensures that files remain accessible even as technologies evolve. Proprietary formats can become obsolete, making access to old documents difficult or even impossible, whereas standardised formats guarantee future accessibility.
Security and compliance with standardised formats
Adopting standardised file formats also plays an important role in complying with standards and regulations. This applies above all to highly regulated sectors such as finance, healthcare and law. For example, formats such as PDF and XML support encryption and digital signatures, guaranteeing the integrity and authenticity of documents. Likewise, the use of open standards makes it easier to implement consistent security measures and comply with regulations such as the GDPR (General Data Protection Regulation).
Efficient storage and indexing
Documents stored in standardised formats are generally easier to index and search within document management systems. For example, by using structured formats such as XML or CSV, platforms can organise large volumes of data more efficiently. This is particularly useful when working with databases that require documents to be searched and retrieved quickly.
Main standardised formats for document management
PDF/A
PDF/A is a standardised version of the PDF format, designed specifically for archiving digital documents. This format ensures that documents keep their integrity and original appearance, regardless of the software used in the future. The file directly embeds all the elements needed to reproduce the document (such as fonts and colours). As a result, it is ideal for long-term storage.
DOCX
The DOCX format, widely used for text documents created in Microsoft Word, is an open standard based on XML. Its popularity and compatibility make it a common choice for documents that require ongoing editing and frequent exchange between users. In addition, DOCX is compatible with most document management platforms and is easy to convert into other standardised formats, such as PDF.
CSV and XML
For documents and databases with large volumes of structured data, organisations widely use the CSV (Comma-Separated Values) and XML (Extensible Markup Language) formats. Both formats are highly efficient for sharing and exchanging data between different systems. While CSV is ideal for tabular data, XML is more flexible and better suited to complex data, and it is widely used in enterprise system integrations.
TIFF
TIFF (Tagged Image File Format) is a very common image format for scanning and storing high-quality documents, such as signed contracts and legal documents. Its ability to maintain quality without data loss makes it a reliable choice for digitising important documents.
Challenges and considerations when implementing standardised formats
Resistance to change
Implementing new standardised formats may meet resistance from users who are used to proprietary formats or specific tools. In addition, the transition to new standards requires training and changes to workflows, which can create an initial learning curve.
Cost and complexity of standardised formats
Although standardised formats guarantee compatibility and security, adopting them can involve costs. This is mainly the case if the company needs to migrate large volumes of data to new formats. Converting old files and adapting systems can take time and require investment in specific tools.
Compatibility with legacy systems
In companies that use legacy (older) systems, adopting standardised formats may face limitations. These systems often do not support modern formats such as PDF/A or DOCX. Consequently, interim or customised solutions may be needed to ensure compatibility.
Which format to use for each type of document
In practice, the choice of format depends on the purpose of the document. The following table summarises the most common options in a document management platform:
| Document type | Recommended format |
|---|---|
| Certificates, declarations and final contracts | PDF/A, preferably with a digital signature |
| Documents in progress | DOCX or ODT |
| Lists and tabular data | CSV or XLSX |
| Data exchange between systems | XML or JSON |
| Photographs and technical images | JPEG or PNG; TIFF for archive scans |
In this way, each document is stored in the format that best serves its use and preservation.
PDF/A and digital signatures
PDF/A comes in several versions. PDF/A-1 is the most restrictive, while PDF/A-2 and PDF/A-3 allow more features, such as transparency or attached files. Moreover, PDF/A can contain digital signatures in the PAdES format, which is recognised across Europe. It is therefore a good choice for documents that need to retain legal value for many years.
Practical example: Standardising contractor documents
Imagine a platform that receives documents from contractors in a wide variety of formats: photos taken with a mobile phone, Word files, HEIC images and password-protected PDFs. Consequently, validators waste time opening files, and some are even illegible.
The company decides to accept only PDF and to automatically convert the images it receives. At the same time, it publishes simple instructions for contractors on how to scan documents. Within a few weeks, the reading problems disappear and the archive becomes more consistent and easier to preserve.
How to define a format policy
For standardisation to work, there should be a simple policy that everyone knows. In general, this policy specifies the formats accepted at each stage of the document lifecycle, the conversion rules for archiving and the permitted exceptions. It should also explain how to validate files, for example by checking whether a PDF complies with the PDF/A standard. Finally, the policy should be reviewed periodically, because formats and tools evolve. In this way, the organisation ensures that documents remain readable and usable in the future.
Frequently asked questions
Is a standard PDF enough for long-term archiving?
Not always. A standard PDF may depend on external fonts or resources. PDF/A, by contrast, ensures that all the necessary elements are included in the file.
Should compressed files, such as ZIP, be accepted?
In general, this is not recommended. Compressed files make it harder to preview, search and run security checks on documents.
How can old documents be converted to PDF/A?
There are tools that convert and validate files in batches. However, it is advisable to test a sample first, because some old documents may lose elements during conversion.
Conclusion on standardised formats
Adopting standardised formats in document management platforms is an essential step towards ensuring the efficiency, security and longevity of digital documents. By choosing formats such as PDF/A, DOCX, CSV and XML, companies ensure that they can share, store and retrieve their documents effectively, regardless of future software or technologies. Although there are implementation challenges, the long-term benefits far outweigh the initial costs. For this reason, the choice of standardised file formats should be a strategic priority for any organisation that wants efficient document management.
