Frequently Asked Questions
Here are some common questions and answers about ett file conversions ask by our users on RunConvert.com.
Frequently Asked Questions
Q: Will pivot tables stay intact after conversion?
A: If you convert between Excel-compatible formats like XLSX or ODS, pivot tables should stay. CSV or PDF will flatten them to plain data.
Q: What format should I use for importing into Excel?
A: XLSX is the native format, but Excel also works great with CSV and ODS.
Q: How do I know if the converted file is accurate?
A: We recommend opening and scanning the result before sharing. Most conversions are spot-on, but it’s good to double-check!
Q: Can I convert a spreadsheet into JSON or XML?
A: RunConvert doesn’t support that just yet, but it’s on the roadmap. For now, you can use tools like Excel-to-JSON converters online.
Q: Can I convert scanned spreadsheets?
A: Not directly. Scanned files are usually images or PDFs, so you’d need OCR (optical character recognition) first—then convert.
Q: Is there a limit on how many times I can convert?
A: No limits for basic use! Convert as many spreadsheets as you want—no strings attached.
Q: What if my converted file looks different?
A: That can happen—especially when jumping between formats that support different features. Just check your data and reformat if needed.
Q: Can I convert a spreadsheet to HTML?
A: Yes! It’ll turn your spreadsheet into a web-friendly table that you can embed or share. Super useful for data reports or dashboards.
Q: Does RunConvert support right-to-left languages like Arabic or Hebrew?
A: Yes! Just make sure your original spreadsheet is encoded in UTF-8. We handle RTL text without issues.
Q: How long does a spreadsheet conversion take?
A: Usually just a few seconds. It depends on your file size and internet speed, but it’s faster than brewing a cup of coffee.
What is ETT (Extended Text Table)?
ETT (Extended Text Table) is a file format used to store structured text data in a table-like format, often used for more complex data sets that require extended metadata beyond simple tabular values.
ETT files are typically used in advanced data management systems, where each row and column can have additional descriptors, allowing for detailed organization and categorization of data.
How to open ETT?
ETT files can be opened using advanced text editors like Sublime Text, Visual Studio Code, or any IDE (Integrated Development Environment) that supports this format. They may also be opened with specific database management tools that can process extended table data.
To open ETT files in spreadsheet applications, the format might require a plugin or extension that adds support for the structure of the table.
