Successful migration of 50 years of files

DCL assisted my publication migrate 50 years' worth of outdated PDFs into XML for a new website on the Silverchair publishing platform.

At the start of the project, there was a learning curve on both ends in understanding the scope of the work. During this time, extensive communication was vital to align expectations and meet the needs of both parties'.

For the final packages, I was very impressed with the efficiency and attention to detail from the DCL team. They swiftly and frequently addressed any errors in the upload process. They took my feedback seriously, demonstrating a commitment to deliver the best product possible.

I had a strict budget, and they consistently updated me on estimates. I worked with David and Devorah, both of whom were kind, respectful, knowledgeable, and communicative.

Since our initial project, I have worked with DCL multiple times on additional file conversion work and have continued to receive excellent deliverables and customer service.

DCL really goes above and beyond

DCL employees really go above and beyond (specifically, Howard, Kajal, and Sergey)! We are new to this work, and they always answer our extensive questions with patience and in a timely manner. If they don't know an answer, on many occasions they have followed up and chased one down for us. They are efficient, professional, fast and just great to work with. Highly recommend them for conversion needs and really appreciate their efforts :)

I was unhappy with the previous ebook…

I was unhappy with the previous ebook version of my book, and someone recommended I call DCL for assistance. They took my manuscript and converted it into an ePUB file in less than a week for a reasonable price. I was then able to quickly upload it to Amazon and Barnes and Noble and get it out there for sale. I was impressed with Allan and the team and would recommend them to others who need similar help. Thanks DCL.

Great service for eBook conversion

Mary Jane and Allan at DCL Conversion Laboratory have converted several of my books to eBook format. These books contain numerous data tables that require special attention and care. DCL's communication, expertise, attention to detail, problem-solving skills and speed of delivery are excellent. Mary Jane and Allan are a joy to work with.

Exceptional!

DCL was incredible to work with, especially Mary Jane. It was my first time converting a PDF to a reflowable EPUB and she was so knowledgeable and patient throughout the process. We will certainly be using them again!

Having no experience with this process myself, David, Leo and their team could not have made it easier. They guided us through the whole process and their team is responsive, communicative, fast, and very reasonably priced. I am honestly not used to having just an easy experience with a new vendor—every step of the process was a pleasant experience. Thank you for all the help!

Thank you from the UK

As a pharma company in the UK, we needed someone in the US to deal with FDA matters & DCL did just that. Their service, communication and customer support was second to none. The whole team were fabulous but a special thank you to Howard for his patience.

Thank you, DCL and Jannie.

I am pleased to have worked with DCL. As a new author, I attempted several free online sources to convert my manuscript from a docx or PDF to an E-book. That was a waste of time considering I needed to upload documents on different print-on-demand platforms. None of those conversions turned out as one would expect. I wish I'd found DCL before choosing those free but time-consuming services. DCL's price was reasonable, and the conversion was great --especially on Calibre. The communication by email with Mary Jane (also known as Jannie) put me at ease.
I appreciate the easy communication via email with her. I am a first-time author learning the different phases of the craft as I go along. I get anxious when I anticipate communicating with someone more experienced in the field than I am. Going forward I am nixing the free online sites and immediately turning to DCL and Jannie with any future conversions.

DCL is a great partner

We've worked with DCL for several years, both on content conversion projects and when using Harmonizer. They're incredibly knowledgeable, professional, and do great work. I've been very happy with everything they've delivered. Love the way they innovate. Their Harmonizer product has only improved over the years. Great stuff!

The team at DCL is always prompt and consistent

The team at DCL is always prompt, professional and quick with their responses and their turn around time is always on time and consistent. I also appreciate Kajal and Sergey always being patient when I make a mistake, ask questions and/or send wrong documents. There is never a feeling that I am wasting their time.

I appreciate the whole team as sometimes I have a strict deadline. DCL always pulls through. It is noticed and appreciated.

Thank you all!!

Migration from one CCMS solution to another

DCL assisted in migrating our technical user documentation from Author-it to Paligo. The process included working together to create the import path for the migration to occur, including mapping XML structure between components and elements in both tools.

Because DCL had not previously worked on a migration of Author-it to Paligo, we experienced some miscommunication in understanding each other on scope of the project, volume of content to be migrated, and complexity of mapping the structure and use of content between the solutions. This extended the time and effort needed to set up the import path. It also meant much more time and resources from our own employees than expected.

Despite the learning curve from both sides, DCL worked with us throughout the process to create and troubleshoot the import path. Once in place, DCL migrated all content from one solution to the other. They were flexible and we worked together to find a path forward when the project extended much longer than either of us expected. They were always great to work with. The end result meant much less time for our team as a whole to transfer and clean up content.

DCL Caters to our specifics cases very well

Our products have specifics in packaging and nature of business setup which can be tricky. DCL (Data Conversion Laboratory) always were able to place those specifics aligned well with FDA system; from support in creating SPL files, onto submission to FDA Gateway, troubleshooting from errors and path forward as FDA guidelines would state, always brought to success submission with our NDC, facility update, and annual update! DCL team very courteous, professional, and timely manner. Happy customer here.

Excellent PDF to EPUB Conversion

I have worked with DCL and Mary Jane Lopez for several years and they consistently provide excellent PDF to EPUB conversion services and customer service. They are quick and very responsive and do great work. If you're looking for a more dynamic EPUB eBook experience, that's not DCL's wheelhouse. For basic EPUB conversion services, I highly recommend them.
