6A practical guide to documents & files workflows
The best tool is the one that matches the input, decision and destination—not simply the broadest label.
Preserve meaning across document formats
DOCX, plain text, Markdown and HTML represent structure differently. A conversion may retain headings and paragraphs while losing comments, tracked changes, fields or complex page layout. Keep the source file and review the result in the application where it will be used.
Treat tables as data, not just text
CSV, TSV, spreadsheets, JSON and XML encode rows and fields with different rules. Before conversion, identify the delimiter, text encoding, headers, date conventions and nested structures. Cleanup and duplicate tools should operate on a copy when the data is important.
Inspect files before opening or sharing
MIME inspection, hashing and archive viewing can help identify a file and compare it with an expected copy. A matching hash supports integrity checking but does not prove a file is safe. Archives also require path, size and compression-ratio limits when processed on a server.
What you can work on
Tool outputs support review and decision-making. They do not replace professional judgment, source verification or the rules of the platform receiving your work.

Processing should match the task
Catalogue search runs locally in your browser. Functional tools will identify when work can stay browser-local and when a server, authorized public data source or semantic service is necessary. No universal privacy or outcome guarantee is implied.

Documents & Files questions
Clear guidance for choosing and using the catalogue responsibly.
Will DOCX conversion keep all formatting?
Basic structure often transfers, but complex layout, comments, fields, embedded objects and tracked changes may not.
What is the difference between CSV and Excel?
CSV is plain delimited text with one table; Excel workbooks can contain multiple sheets, formulas, formatting and richer types.
Can JSON and XML convert without information loss?
Not always. Attributes, namespaces, ordering and mixed content can require explicit mapping choices.
What does a file hash tell me?
A cryptographic hash is a fingerprint for comparing bytes. Matching trusted values supports integrity verification.
Is a MIME type the same as a file extension?
No. An extension is part of the filename; a MIME type describes the intended media format and may be inferred or declared.
Can ZIP viewers open every archive?
Support depends on archive format, encryption and compression method. Damaged or unsafe archives may be rejected.
How should text encoding be handled?
Use the source encoding when known; UTF-8 is a common interoperable choice, but conversion can corrupt characters if guessed incorrectly.
Should I process the original file?
Keep an untouched original and review the generated file before replacing or distributing anything important.
